The technical field

This invention relates to a method of data transmission between the stations of departure and destination in the multistation communication network, the communication network for performing this method, and communication apparatus for use in the network.

Prior art

Known networks that require one or more control nodes or base stations through which should be channeled messages from the station of departure to the destination stations. Such networks are vulnerable to damage nodes control devices or base stations. In addition, the control communication nodes or base stations have a relatively high cost, and the remote station in the network is limited against movement relative to the base stations.

Connectivity between the stations in such a network may change due to relative movement between the remote stations and the base station, interference, noise and other factors. In the situation of Rayleigh fading the intensity fluctuations of signal strength, noise and interference changes the connectivity between stations in the network instantly, making any way fixed routing or adaptive routing through the transfer of routing information between stations is almost impossible. To compensate for the interference and fading, messages are transmitted with redundancy and with sufficient the OI power for guaranteed admission, which leads to quasi-optimal usage of the network to interference between stations. Quasi-optimal network utilization leads to lower network bandwidth (Erlang) for a given area and a given spectrum allocation.

Description of the preferred embodiments of the invention

The present invention has primary application in wireless data networks, including mobile radio or telephone network cell the structure of the service areas, bilateral network signal transmission system of the search call, the data network public telecommunications network (OTS) bursts meteor showers and environmental conditions of the satellites in a low orbit and satellites in stationary orbit, where it is rapidly and strongly varying connectivity and changes in aggregate platforms prevent the use of conventional methods of creating a network connection.

Developed communications network, which uses adaptive coordinated communications between stations in the network. The network is the complete network with nodes, which provides a rapidly changing connectivity between stations and dynamically routes messages between stations on a shared basis to improve data throughput in the network, minimizing energy consumption and interference between stations.

The invention optimizes network bandwidth by guaranteeing an optimal use of the available spectrum on the basis of throughput (Erlangen) for this area, this allocation of spectrum and the value of information (erlang-km2-Hz-dollars).

Let us first consider figure 1, which schematically shows one station network in simplified form. It should be understood that the network stations can be portable or stationary transceivers stations or the combination.

The base station is a control device 10 on the basis of microprocessor that is running software that receives information through the control transmission from other stations, and both are carried out continuously under the action of special sounding signals transmitted by the station. The station has one or more transmitting antennas 12, which is connected through the block adder 14 to the adaptive receiving device 16 and the adaptive amplifier power - transmitting device 18, and these connections are controlled by the control device (controller) 10. Data flow between the controller 10 and the receiver 16 and transmitter 18 through adaptive modem (modulator-demodulator) 20 data transfer rate. The input circuit 22 receives, for example, a voice signal, data and/or video signals, and analog-to-digital converters with appropriate adaptive coding processors under the control of the controller 10 converts the signals into a digital format and sends them to the controller 10.

The controller 10 each station continuously analyzes the data received from other stations, which are within the range that appears from time to time because of their communication and interaction. Thus obtained address information for the other hundred of the Nations is collected and stored, and converted into information connectivity. The controller waits and monitors the activity of other stations, looking for an opportunity for them to convey the message as the departure station, or to relay messages to another station on behalf of another station of departure. When the controller detects a quiet time in the network, it transmits a sounding signal, which, incidentally, contains its own address and the address of the destination station.

When you receive a confirmation signal from the other station, which can act as an intermediate station or relay station, the controller in this case transmits the data packet containing the message (either a valid message, or relayed message). Energy transfer, data transfer rate, the duration of the message, the message priority, the lifetime of the message, the baud rate and other parameters are managed in accordance with the information obtained from the confirmation signal relating to the characteristics of the channel or the communication line between the stations at this time. Synchronization transmission is chosen so to take advantage of peaks in the signal level or levels of the signal-to-noise typically experienced in terms of Rayleigh fading, to a communication method there is indeed represented adaptable system multiple access time division channels. Thanks to the work in peak mode reduces the required transmit power, reducing interference between stations and reducing the need to transfer messages.

The aforementioned maximums may be, for example, from changes in amplitude, frequency or phase changes in the signal path, noise, interference, actions, multipath and so on. The appearance of the maxima can be detected by controlling the physical characteristics of the received signals or by controlling the coefficients of bit-error as a function of time.

Design and operation of individual devices transceivers capable of operating as a station above method, described in more detail below with reference to Fig-13.

Shown in figure 3 state diagram and is shown in figa and 4B block diagram of the algorithm to illustrate the operation of each station in the network. Shown in figure 3 state diagram illustrates the overall operation of the station, then as shown in figa and 4B block diagram of the algorithm illustrious typical adaptable procedure for the transmission of messages.

The main feature of the described system is in continuous control of each station of the activity of other stations on the network and from the point of view of choosing the optimal channel for each transmission and in the selection of the station, which should pen is to give the message. Each transmitted over the network message, regardless of whether it is a data message, as shown in figure 5, or by sensing message-confirmation as shown in Fig.6, contains its address, its destination address and the address of the station relay messages. Therefore, any other control channel station hears what stations broadcast information and what station relay this information.

When passing messages from one station to another, the address of departure and destination in each message remain the same, but the address of the intermediate station is the station address of the relay used for the next "jump" (jump). When a station receives a message, it analyzes the information received from the channel and from stations located around it, and then a adaptable way through the loop sensing handshake selects an address other intermediate stations to relay the message forward through this station. The departure station and the destination station, obviously, may be able to establish direct communication. However, in many cases, the sending station will not be able to communicate directly with the destination station, and is able to transmit the message to an intermediate station that hears the conversation is about the destination station, either directly or through one or more intermediate stations. Each time a message is sent to an intermediate station that cannot perform direct communication with the destination station, it searches the next intermediate station, which is in a state of communication with the destination station, or which hears the conversation with the destination station.

If the intermediate station cannot reach the destination station on any route (i.e. it does not accept information from other stations containing the address of the destination station), it immediately returns to the previous station so that the station may attempt to find another route for the transmission of their messages.

It should be understood that there are at least two different types of messages transmitted over the network: message sensing handshake and message data. Messages sensing handshake is primarily used for adapting the control and feedback, while the data message is used to transfer messages over the network. For data messages, you can use any data rate, while for messages to move it back usually use the standard data rate network. However, the message of the probing signal-confirmation what can be sent at different data rates, allowing stations to install best data rate for specific conditions.

Figure 3 shows a typical adjustable flow mode, send us a message. In the block And the message is entered or accepted for relaying. Then the controller 10 proceeds to block b, where it defines the message priority depending on completed time after it was entered or accepted the message, the priority assigned to other messages in this package, and opportunities that he has, on the basis of statistical data developed in block j for sending the message. He then checks the information on the basis of statistical data and control network, and sets its priority to the message relative to priorities of other messages in the network, taking into account the network load. He then makes a decision regarding whether to control and to wait, when it will be heard by the destination station, or station, speaking to the destination station, or whether to request or send a sounding signal to detect the destination station or repeater (intermediate station) to the station of destination. If the message has a low priority, the controller proceeds to block L and waits in a control mode during the period of time needed to either hear the destination station or translator conversation with the destination station. Using this method, find the route with one or two transitions.

To set the time on the basis of priority, the controller passes to block E where it waits for an opportunity to transmit through the out break in network activity and suitable conditions in the channel, and then makes requests or sends probing signals in relation to the destination address in the block N. If the destination station accepts, the controller proceeds to block I, where he sends on the basis of the adaptive feedback message to the destination station. The controller then returns to the mode control unit D.

If the sounding signal is not accepted, a confirmation from the destination station, the controller in this scenario explores the possibility of transmission through the relay station or an intermediate station (block G), and on the basis of the adaptive feedback from any such relay station sends a message via the relay station (block F). Depending on the results of the inverse return messages from the repeater, the controller returns to the mode control unit D.

When a station sends a sounding signal, it can explore any one of a specific group of stations, or to send a sounding signal to the station that "hears" the transfer to a specific station. Thus the study can be used to determine the location of other stations or detection capabilities of communication with other stations.

When the relay station or an intermediate station successfully transmits the message forward, it sends a signal to move it back together with more adaptive information to the sending station. Then the departure station returns to the mode control unit D and is awaiting confirmation of continuous messages, as well as any additional requests for retransmission of messages when receiving messages. When the message reaches its specific destination, the destination station sends back an acknowledgement message, which can be followed, due to the adaptive adaptable network completely different route back to the station of departure.

The message of the probing signal - return return used by the network stations used in an interactive way in analog mode for people communicating through the "." in an attempt to attract attention to each other, "swinging" to see a successful connection and other adaptive relationship with the aim of modifying various parameters of their relationship.

It should be noted that the network stations are controllers, base stations or upstream stations not in the hierarchy. The network hierarchy is fully distributed and only the message priority and the possibility of transferring determine sweat the messaging. Thus the network stations work together to maximizing the total throughput.

One of the goals of the overall network is shared to maximize throughput based on erlangb for a given spectrum allocation this field and this funding hardware infrastructure. In other words, the network aims to maximize the value of Erlang-km2-Hz-dollars.

It should be noted that the information assigned to the route does not pass over the network or from the structure of the data message or in the message structure of the sensing signals of confirmation, as for passing data over the network does not require special routing information.

Under normal conditions, the controller each station is either in the D-block or block N (3) state diagrams. In other words, it is either the control or anticipation of the possibility of transmission in high-level network or adaptive query, and receive a random feedback signal in the inactive network. The reason for the query is to create activity messages, or to find a particular destination station or the relay. In case the capacity of the station is not sending the sounding signal, and rely on listening to other stations, connecting with each other by myself is m information, connectivity, and routing. Thus, normal operation typically contains a waiting connection with the destination station, and then an instant and flexible way of sending messages either directly to the destination station or to an intermediate station, speaking with the destination station.

Describes the communication network has a number of special characteristics:

1. The network allows any station to enter the network without requiring adjustment of the lists of network or information transformation network;

2. The station is able to dynamically adapt to each other joint to maximize message throughput and minimize competition between stations;

3. The station is capable of feeding the excitation signals and to request a channel between them with the aim to detect features connectivity;

4. Plants are able to use the verification callback return, dynamically adapting thereby operating parameters to each other and informing others about the state of the message flow (for example, arrival of a message, queries, sending messages, and so forth).

5. The station is able to listen and to form the basis of knowledge that allows them to make optimal first attempt when sending a message over the network, on the basis of the obtained control information and clicks the things from the other stations.

6. The message sent is not a fixed way. If no confirmation message is retransmitted. Messages that are "stuck" in the network, making a "short break" after setting a certain period. In the message, enter the time (duration) of the message, the lifetime and the time of generation. This allows you to shape the transmission of time sensitive data over the network depending on its remaining lifetime, and also allows you to provide a brief interruption of the transmission of time sensitive data (type voice data)that are not appropriate.

7. The station has a "smart" package network messages. When you hear any specific station, you can dynamically get out of the package the right message to send to this particular station in order to maximise the opportunities for transmission. Thus, when the station routes the message on behalf of a number of different stations through a number of various other plants, it can adapt the method to combine messages and pass them on to other stations, reducing the cost of the network.

8. Each station can control the quality of the communication line or channel based on the signal level, interference, signal-to-noise maximum noise and so forth, to find the best opportunity is for sending messages during periods of relative silence and optimal signal level.

9. Stations have the ability to pass the minimum required power level required to reach the destination or intermediate stations, thereby minimizing interference to other stations. The transmit power is adapted on the basis of the separate transmission and increases or decreases based on the information contained in the signals, checks the back of the return from the other stations. Routing and relay signals are optimized so as to minimize the number of stations transmitting at high power, thereby minimizing interference and energy consumption.

10. Stations are always trying to transmit, using the peaks of the channels, based on availability, using a reduced signal level and additionally minimizing interference to other stations.

Describes the communication network has a number of advantages in comparison with known systems, for example, if the station itself is in conditions of high noise, it can relay a message to a neighbouring station, outside the presence of noise, which, in turn, may further relay the message to the destination station. Alternatively, the station in conditions of high congestion can reduce the levels of its capacity to effectively minimize interference, and to relay messages is between each other on the low power and high speed data transfer, effectively thereby using less time on the public network. The network can clearly be connected to the normal network mnogovershinnoe constant routing with full transparency. For example, if transmission of the message from the departure station to the destination station will require more than the usual 3 transitions, the message can be routed to a fixed network, which uses normal routing. In the above-described dynamic network will occur again 3 final transition.

In the described network messages are routed "towards their final destination in one hop relay at the same time, because each station develops routing information for each destination, and the departure station there is no need to rely on their own information to determine the route of the program. Because in many cases the last transition to the destination station is more difficult, the message may go through a number of additional transitions to reach its final destination. Therefore, even in case of a normal system with 3 transitions, because 3 of the transition are available at each intermediate station, to reach the destination station, you can use 10 or more. The reason is that each sub is full-time station is a new solution for how to reach the destination station, and every time available 3 additional transition. Previous races are not held in memory, not counting the sending station. This method emphasizes the importance of confirmation "continuous" message, because in some cases the message can reach the effective dead-end, where there is no possibility related intermediate stations to listen final destination after a maximum of 3 additional intermediate stations.

Shown in the figure 2 example, it is assumed that the sending station 24 initially hears the intermediate station 26 that communicates with another station 28 and, therefore, sends the message that it wishes to transfer station 28 through the station 26. If at this point connectivity between stations 26 and 28 is lost, the station 26 can accept adaptable solution to send a message, for example, through another station 30, which has a higher connectivity to the station 28. It should be understood that the routing change from station 26 through the station 30 station 28 does not depend on the departure station and is adaptable decision taken at station 26. Similarly, if the station 30 detects that it can not directly contact with the station 28, it is also adaptable way finds an alternative route and, in the can, will relay your message through another station 32.

When adaptable way relaying attempt to minimize the number of clicks absent, but rather try to maximize the network bandwidth and the speed of flow of the message. Many transitions can be dynamic and adaptable way to achieve this optimum. Because each transition check back returning eliminate competition and overloading any particular station, and the confirmation of the break (lifetime) messages and continuous messages prevents message loss in the network, clogging up the system or never reaching its destination, as may occur in networks with avalanche routing, described the network is extremely reliable compared to the static routing, adaptive routing, or algorithms, flooding.

As described above, the network uses a nondeterministic way the optimization and the network relies on the adaptive feedback on a collective basis, impossible method of closed form prediction system throughput or latency. Method of determining these parameters is only modelling and research-based modeling in order to determine the value of parameters in the network.

As the network stations receive information from past results and adapt to the resulting control changing conditions, the flow of messages to themselves and between other stations controlled by the activity of other stations and adaptive feedback other stations, groups of stations, routing messages in the network, they can be considered as interactive creators of the collective decisions of the organization. Each station has a tool of artificial intelligence, which produces a routing variables and parameters adaptation. The parameters obtained from the instrument control and long-term database (Fig), role models of learning that are required for artificial intelligence. Then the weights of different parameters in artificial intelligence regulated and trained on the basis of a dynamically changing network settings. Since the stations are adapted to each other, the overall network can be viewed as a processing system with a strong parallel distribution, with the ability to configure routes for data flow and adapting the transmit power and other parameters of each station with dynamic learning. This provides a near-optimal data flow through the network and optimizes network bandwidth.

As lternative, the network can be viewed as a processing system with a significant parallel distribution with the ability to configure parameters such as transmit power, data rate, speed and duration of the transmission of signals through dynamic learning. This allows the dynamic perception of load conditions and changes in propagation conditions, measured across the entire network. Therefore, the network can be operated in such a way as to optimize the load of messages by adapting one or more parameters.

As the underlying network Protocol is very simple, requiring only two basic types of messages described above adaptive feedback opportunities, to actuate each station in small networks with low bandwidth, you can even use a very simple artificial intelligence. When extended network "intelligence" of stations can be increased without increasing the underlying communication protocols. Because routing information is not passed across the network, you can mix station with low and high "intelligence" without compatibility issues.

Because the network is a cooperative network, the level of service that can "guarantee" users, is only in its basirov the Institute on the priority level and the size of the network. When the network load is high and delay increase, to the network, you can add additional stations, some of which are connected with the more traditional networks with high bandwidth, thereby preserving the overall message flow. However, conforming to the invention, the network never catastrophically not subject to this disadvantage, because there is no single point of failure type or base station controller node.

Different users may have different priority levels. For example, some users may have access to higher transmit power or quality of production cycles, and the ability to type messages with the introduction of higher priorities, as well as the chance to re-enter the message, even if not accepted continuous confirmation. The described system allows to combine in a shared network users with high priority and low priority.

Now consider Fig.7. This diagram is used to explain the probability of a flow of messages through the network. At the stage of departure And entered message and adaptable way, it is expected any station that has a high probability of routing messages to the destination station. Assume that the stations closest to the item specifications, the Oia, have a higher probability of binding to a destination. Most likely the relay is, for example, from station a to station C. Assume that the maximum capacity between the departure station and all stations from V to About, adaptable environment you can route the message directly to the destination from the departure station, but it has a very low probability.

From the first repeater In the message can be sent to any of the stations G-O. Suppose that on the basis of capability message transmitted from station b to station I. in this case, the station I can transfer to any of the stations from L to O. Suppose that station I transmits a message to the station M, where the most likely route will be the destination station O.

Therefore, when a message is routed through the reduced number of stations with a higher probability of binding to the final destination station until the last transition will only have one choice. That's why you want the network to do a number of opportunities intermediate transitions as much as possible, and the transition to the penultimate relay be chosen in such a way that the last transition was a very high probability of success. Online higher speed surveys the project and higher overall activity of the network increases the number of opportunities and therefore, the probability of detection capabilities. When routing messages to the destination and the decreasing number of "elections" should decrease the size of the transitions, in the alternative, to increase the transmission rate or the signal level sensing. This underlines the importance of "extra" transitions that may be necessary to carry out the last one jump extremely high probability. Since the system always looks at 3 forward, you can ensure that the last transition has a higher probability.

Since the cumulative probability of receiving a message from the departure station to the destination station is an intermediate product of the probabilities, the network aims to keep the success probability of each transition as close as possible to the unit. Equation 1 gives the probability of success of one transition

where: Pi- the probability of transmission to the station with some connectivity to the station of departure and higher connectivity with the destination station, and n is the number of stations.

The probability of each intermediate transition depends on the number of "elections". Therefore, even if the intermediate transitions are low probability, the probability of detecting any one of them high. Why is the big transition with a low probability can be done at the first passages, providing the latest transitions high probability. In this case the total probability, which is the product of all probabilities of the intermediate transitions, turns out to be high (equation 2)

Psum=Pper×Pper× Plane 3(2)

For example, a low power station with low connectivity between them can route messages on behalf of each other to the end points, provided that they are sufficient. In the case of network vehicles, the vehicle can relay messages to each other and to the stationary control centres, which have a higher power and duty cycle and provide a high probability of the last transition to the vehicle destination as soon as messages are routed close enough to them from other vehicles.

Similarly, in the case of the universal terms, where home remedies have a station with low power and low performance, messages can be routed from house to house, until it is sufficiently close to the station data collection or dissemination of data, which has a higher capacity and a higher fill factor and which can guarantee a high probability of the last transition.

Individual stations can prisposablivat is a relatively "clean" message, to improve connectivity. For example, if the first station associated with the second station, the third station, which determines that it is better to act as a relay between the first station and the desired destination station or that it can act as a relay between the first and second stations may actively interfere with the purpose of acting as a repeater, thereby allowing the first and second stations to reduce its power level.

Therefore, the advantages of the system can be summarized as follows:

1. Providing more options;

2. Guaranteeing that the probability of intermediate transitions together gives you a high probability;

3. Ensuring that the message is routed to the endpoint relay, which has a very high probability of reaching the final destination.

4. Always the routing of messages to stations with higher connectivity.

On Fig, 9, 10 and 11 is illustrated in more detail by the hardware shown in figure 1 station. A test station, which is described below, was made in the form of a portable radiotelephone transceiver for use in a voice communication network. Sample transceiver is designed to use the as installed on the vehicle unit and was constructed in the housing, which can be mounted under the dashboard or in the Luggage compartment, for example, of the vehicle and which is powered by 12 volts DC power from the electrical system of the vehicle.

It should be understood that the transceiver can be performed in miniaturizing form powered by rechargeable batteries for use as a personal transceiver or can be used as a base station or a fixed relay, for example, mounted on a tower or mast with a corresponding effective antenna.

Diagram of the transceiver is built through a series of modules, which correspond to the blocks on Fig, 9, 10 and 11 are flowcharts. On Fig shows the module transmitting device transceiver containing adaptive amplifier power range output power from minute 40 dB (-40 dB), measured relative to level 1 mW, up to 70 watts, the modulator manipulation of minimum phase shift (MPS) frequency synthesizer with two speeds of 8 kilobits per second and 80 kilobits per second, the circuit on and off the power supply and protection circuit power. On Fig shows a scheme of the power measurement and the attenuator in the transmit-receive transceiver.

Figure 9 shows the module of the receiver of the transceiver, which includes the low noise transmission is AMI pre-amplifier frequency Converter, two stage intermediate frequency amplifier (if amplifier) and two demodulator MMPS, operating at frequencies of 8 and 80 kilobits per second.

Figure 10 shows the main transceiver microprocessor together with the corresponding device and the control circuit, while figure 11 shows the microprocessor together with the scheme of conjugation of two vocoders and other user interface elements.

On Fig shown that the antenna 100 is connected to the detection circuit signal low power 101, the switch acceptance 103 and the measurement circuit of the power of the direct signal and the reflected signal 161 to the amplifier 145. An amplifier 142 and 144 of the video signal from the buffer amplifier 140. The buffer amplifier 140, in turn, receives the output signal of the generator, voltage-controlled (VCO) 139, which forms part of the circuit of the modulator-synth. In this scheme, the synthesizer 138 operates at a frequency of transmission in the range of 45 to 50 MHz and is the two-point frequency modulation, which means that the signal of the reference frequency source 137 for the synthesizer is modulated low-frequency component in the transferred data, while the signal VCO is modulated high-frequency component data. Modulation is performed to the respective analog switches 135 and 136, managed with the responsible schema master devices 133 and 134, which receives the data to be transmitted with the corresponding data rate at which the transmitting device. The result is a signal MMFS, which is supplied to the second power transmitting device.

During the reception, the operating frequency synthesizer 138 is shifted a short distance from the receive frequency of the transceiver, where the distance somewhat greater than the width of the band of the wideband if filter in the receiver. This is accomplished by feeding the output signal of the reference frequency 137, which operates at a frequency of 10 MHz, which sets the device, which counts the periods, and when the overflow value of the counter is draining period, reaching into the synthesizer. This allows for fast frequency shift synthesizer during transmission without the need for reprogramming of the synthesizer, when the transceiver goes into receive mode and eliminates delays that could occur when programming the synthesizer during the switching from the reception mode to the transmission mode and Vice versa.

For the successful implementation of the network that are relevant to the invention transceivers, it is important to control the transmission power so that it was sufficient for the signal path used in any m is the moment, but not excessive, which would result in undesirable power consumption and interference between neighboring stations. Based on its control channel you are using the schema processor transceiver generates a control signal power using the control circuit power 141, which is supplied to the comparison circuit 143 that contains the control circuit gain and low pass filter. The comparator circuit 143 compares the control signal power signal power measurement transmission and generates a control signal that changes the gain of the second predominance amplifier 144 to increase or decrease the transmission power, respectively. This scheme works in such a way as to adjust the transmit power to match the power of the signals received on the same channel, so that transmission occurred at a sufficient, but not excessive level of power.

The buffer amplifier 140 stabilizes the level of the output signal of the modulator VCO 139 at a constant level, whereas the first and second predominace amplifiers 142 and 144 are amplifiers of class 8 with a controlled gain of the second predominance amplifier 144. The amplifier 145 is a class C amplifier and its current consumption is measured with the aim of providing display output transmit power of the transceiver. The scheme of the Communist the Torah 143 provides effective feedback circuit, which regulates the power output of the transceiver in the direction of set value controlled by the control circuit power 141, and changes the output power of the power amplifier from 100 mW up to 70 watts.

To increase the range of output power transmission device, an output path connected controlled attenuator, when required transmit output power below 100 mW. The attenuator can perform attenuation to 60 dB in steps of 10 dB. Thus, the total dynamic range of the transmission can be adjusted in the range of 100 dB. The attenuator 102 contains a diagram of the ladder resistors 200, which are the three groups 201, 202 and 203, with values calculated to provide attenuation of 30 dB, 20 dB and 10 dB, respectively (Fig). The resistors are connected in the circuit and disconnected from it through the use of managed switches 204 containing p-i-n diodes, which are opened or closed by control signals coming from the schema processor of the transceiver.

Depending on the combination of the attenuator sections that are connected or disconnected, the maximum attenuation of 60 dB in steps of 10 dB. Thus, the output transmit power of the transceiver may vary between -40 dB and 50 dB, measured relative to level 1 mW, with fast switching of power levels. This is what allows you to obtain the output circuits of the transmitting device serial data packets with different power levels in accordance with the requirements. Diagram of the attenuator 102 is also used when measuring the input power, since the structure of power measurement 161 cannot work in a very wide range, and usually only works in the range of 60 dB. By appropriate switching of the attenuator effective measurement range of the measurement scheme power 161 extends to 120 dB.

Let us now consider figure 9, which shows that the module of the receiver of the transceiver contains a high-q band-pass filter 104, which is connected to the switch of the transmission-reception 103. The filter 104 has a bandwidth approximately equal to 1.5 MHz, and low insertion loss. After the filter 104 should low-noise pre-amplifier 105 with high dynamic range, the output of which is fed to the mixer, forming part of line 10.7 MHz. The output signal of the mixer through a band-pass filter 107 is supplied to the first if amplifier with high gain 108. The output signal of this amplifier is fed to the first and second ceramic filters 109 and 110, which provide bandpass filtering frequency 150 kHz with a center frequency of 10.7 MHz. After the filters 109 and 110 is the second if filter 111 for compensation brought losses. After the second if amplifier 111 is connected an additional filter 112 with the same characteristics as the filters 19 and 110; the filter 112 is designed to further improve the selectivity of the receiver. This filter also provides a time delay that is required for damping noise (as described below).

The filter output signal 112 is fed to the circuit damping noise 113, which is essentially controlled by a switch controlled by the output signal of the amplifier 126, which provides quenching output pulse and is used for "clearing" of noise pulses with attenuation of 40 dB when open. The output signal of the circuit damping noise 113 passes through a narrow-band 15 kHz quartz filter 114, which provides a selectivity of 15 kHz with a center frequency of 10.7 MHz. The output signal of this filter is fed to the third if amplifier 115, which has sufficient gain to overcome the losses of the previous stages and to provide sufficient levels of the output signals to actuate the subsequent integrated circuit FM (frequency modulation) 116 NE 615.

From the above we can see that the line of the inverter module of the receiving device provides amplification and selectivity in two frequency bands simultaneously, namely 150 kHz and 15 kHz. This allows simultaneous measurement and demodulation in two different frequency bands and at two different speeds. The use of p is parallel demodulation circuits with parallel data synchronization and data demodulation allows the simultaneous demodulation of data from two different stations at two different speeds, when choosing one of the two on the basis of adaptable solutions.

Integrated circuit FM NE615 116 is used to perform the line amplifier (intermediate frequency amplifier) at a frequency of 455 kHz. The device integrates the inverter frequency oscillator, two limiting intermediate frequency amplifier, quadrature detector, the diagram is noiseless setting, the power indicator with logarithmic reception (IMLP) and the voltage regulator.

The output signal from the third if amplifier 115 is converted to the integrated circuit 116 in the signal frequency 455 kHz, which is fed through a ceramic filter 117, having a bandwidth of about 15 kHz with a center frequency of 455 kHz, and then amplified to create the output signal IMLP. This amplified signal is passed through the second ceramic filter 117, providing additional selectivity, and again increases, providing a total gain of 90 dB. This provides the possibility to measure the received signal strength in the range of -130 dB -30 dB, measured relative to level 1 mW, i.e. in the range of 100 dB. The measurement range is extended to 60 dB, due to the use of switched circuits attenuator 102 (described above) to provide a total range of measurement, equal to 160 dB.

Integrated circuit 116 includes a quadrature detector cells Give is the which works in conjunction with a quadrature phase shifter 118 to provide demodulation of the FM signal, the incoming data with minimum shift keying phase shift (MPS). This waveform data is supplied from the output of the quadrature detector through the filter and appears as a narrow-band output (8 kilobits per second). The use of quadrature detector provides coarse and effective method of demodulation, which is immune to treatments, frequency and phase distortion and does not require time to recover the carrier.

On a broadband line amplifier the signal from the output of the first ceramic filter 109 at a frequency of 150 kHz. Line amplifier includes an amplification stage 119, the output of which is fed to an integrated circuit FC FM signal 120 containing the chip 604 NE. This device is a low-power system FM FC containing two limiting amplifier intermediate frequency (if), quadrature detector, the diagram is noiseless setting, the power indicator with logarithmic reception and a voltage regulator. In the integrated circuit 120 uses a ceramic filter 121 to the frequency of 150 kHz to provide a wider bandwidth of the output signal IMLP to the module of the receiving device is able to perform the power measurement signal in a wide dynamic range simultaneously in width is not the frequency of 15 kHz and 150 kHz.

Chain quadrature phase shifter 122 is included in the scheme in order to ensure the possibility of integrated circuit 120 to demodulate data MMPS way similar to that used in the integrated circuit 116.

In addition to the above functions of demodulation data of a wide frequency band and detecting the signal level of the integrated circuit 120 can also be used for damping noise in the received data in a narrow band of frequencies. This is done through the detection of short noise bursts, which are characteristic of narrow strips of very high frequency (VHF) and significantly shorter period of data. For example, in the amplifier circuit (block 116) frequency 455 kHz data detected at a frequency of 8 kilobits per second, which corresponds to a period of binary digits equal to 125 microseconds. If a noise spike occurs, for example, within 12 microseconds, it makes the noise only within 10% of the period of the binary bits. If a noise spike is passed through a filter frequency of 15 kHz, the pulse duration becomes equal to about 60 microseconds, which leads to a significant distortion of the binary bits of the data signal. Therefore, the damping of noise reduces such noise pulses before they enter the filters narrow band of frequencies of the cascade amplifier frequency 455 kHz.

If the typical noise pulse is passed through the filters frequency is 150 kHz 109, 110 and 112 line amplifier frequency 10.7 MHz, the pulse duration is approximately 6 microseconds, and if it is removed before the line amplifier to 455 kHz, it has little effect on the error rate in bits of data frequency 8 kilobits per second.

For this purpose, differential trigger circuit 123 and the clock unit 125 generates short pulses corresponding to the duration of the noise pulse, after passing through various filters. Since noise pulses typically have a duration equal to only nanoseconds, and the pulse duration at the output of filters will be installed approximately 10 microseconds, and therefore, the clock circuit 125 is configured to generate 10-microsecond quenching pulses. This delay corresponds to approximately 10% of the period of the binary bits of the data signal.

The scheme counter bursts and detecting the level 124 in order to detect and to quantify noise bursts, and this can be used as adaptive feedback parameter to select the duration of the transmission data, frequency data, and so forth. For example, if the noise bursts are measured with a frequency of 100 Hz, the data of the wide bandwidth signal can pass packets between noise bursts with intervals of 10 MS, thereby achieving Zn is a major improvement.

The detection signal of the noise burst with a scheme of counter 124 can be used together with the characteristics of errors in discharge and information IMLP to provide a range of adaptive feedback parameters for use in operation of the transceiver.

And finally, synthesizer receiving 160 provides the local oscillator frequencies of 55.7 MHz 60,7 MHz, mix radio frequency 45 MHz - 50 MHz to an intermediate frequency of 10.7 MHz. This synthesizer is required for the transition frequency on the basis of commands from the main processor, regardless of synth gear. 138. The synthesizer can be programmed to switch the frequency steps, which correspond to the channels having the same bandwidth as the bandwidth of the narrowband data. Because narrowband data is located in the channel of 25 kHz, the synthesizer can be programmed to switch on any channel in the frequency band 45-50 MHz by steps of 25 kHz. This allows the receiving device to demodulate, within milliseconds, the data on different receiving channels between 45 and 50 MHz.

Describes the modules of the transmitting and receiving devices perform the action frequency of the transition joint or independent switching of the channels of transmission and reception. It should be understood that while the specific applications you can perform other transmission schemes, types of signals with RA who sirenum range code direct sequence (RSCP).

When the transmission of each station probing signals and the signals received by the monitor, it switches from one frequency channel to another, recording the information in respect of which there are other stations on different channels, and noting their identity, signal strength, transmit frequency and duration of the transmission. In addition to switching between the frequencies of transmission and reception, each station may also (where applicable) to make a choice between different antennas that are optimized in regard to, for example, different frequencies or transmission directions.

A group of stations can move synchronously or semi-synchronously. For example, a group of stations that relay messages on behalf of each other, can switch frequencies and channels in a group. The network described above frequency adaptive method can be considered a form of slow frequency transition frequency scanning, the method of multi-access systems with frequency division multiplexing.

Stations that provide mixing of overlap and bandwidth, and are suitable as appropriate lines of communication in relation to each other, tend to gather on specific channels or skip channels synchronous way. Because the frequency of transfer-acceptance is one of the options fit with testwuide the invention apparatus, it can be changed if necessary using sounding signals and the signals to move it back. For example, one station may request from the other station to move to another frequency in order to "meet" her in this regard is to ensure a suitable line relay or to reduce the load on a different channel.

The frequency of transfer-acceptance can also be used, for example, in the case of data a high priority, where a free channel can be cleaned and use the program on a high-power, high-speed data transfer directly between the two stations.

Certain frequencies can be used as frequency of collection, or connection with multiple transition, full connectivity, where stations are provided with small amounts of information at lower power levels and higher data transmission rates, thereby minimizing their time and maximizing the overall connectivity of the network in the exchange of information. If two stations are able to establish connectivity through a large number of transitions on this channel, they may decide, by coordinating between them (and possibly one or more intermediate relay stations), go adjustable manner on the selected channel, which has low noise, low POM is hee and/or low load to common sources, distance and relay stations. This type of adjustable frequency rate change occurs more often when you need to exchange large amounts of data, usually requiring increased power levels to improve connectivity. If the station is not able to connect to each other at a first selected frequency, they can choose another channel, or return to the original call channel to re-establish connectivity.

Thus, it should be understood that the frequency used between stations, adapts in the same way as other parameters such as transmit power, data rate or sync transfer, with a view to agreeing channel maximum.

Combining adaptive channel transition together with adaptive transmit power and adaptive data rates is an important feature of the invention. Flexible channel switching can be used to find a peaceful channels with low noise or finding the channel with the load to find the specific relay station or destination. Therefore, in the noiseless network station may seek to gather on the same channel, providing efficient use of the channel by passing on the adaptive capacity and adaptivepath data. However, when the load on the channel increases, the station can move in and out of the channel on the adjacent channels to exchange large amounts of data or education subgroups. Individual stations seeking transfer opportunities, you can move between groups of stations operating on different channels, and in some cases, stations may move together as a group from a channel in the channel to secure the transfer.

Since under normal conditions of distribution appear selective fading frequency-dependent frequency interference, the transition channel creates opportunities transfer with different characteristics, which together with other time-varying characteristics of the channel effectively add an additional variable used in the network adaptable conditions.

The action of the above-described execution adjustable frequency transition network is that stations operating as an intermediate or relay stations that can receive a message from a specific station on one channel and switch to the second channel for the effective transmission of the message. For example, the sending station may not know which channel to find the destination station, but through a process of sensing, the relay station adaptable way to take the AET message from the departure station and transmits it to the destination station, he recently heard on a different channel. Therefore, the establishment of channels that use the station, is a distributed function, continuously scanning the numerous stations and helping each other in determining which channels are other stations. If the station is unable to find the destination station, and transmits the sensing signals on a number of different channels, the message is passed on, allowing other stations to send signals to the sensing to the destination station on a different channel.

Full receiving device allows the simultaneous demodulation, synchronization, and data collection at two different speeds with high dynamic range-difference signals. Although described an implementation option is designed for two different data transmission speeds, the concept can be expanded to serve additional parallel data transfer speeds usually are separated by orders of magnitude. For example, in the described receiving device can provide data transfer speeds of 800 kilobits per second, 8 megabits per second and 80 megabits per second, in addition to speed 8 and 80 kilobits per second. In a typical network, you should select the highest data transmission rate based on the distribution of the spectrum to napolnitelej full spectrum. Therefore, the station can call each other, adaptable and dynamic way at any speed data transfer, and all other station can monitor and analyze transmission. Due to the isolation between different data transmission rates in many circumstances, the station is able to demodulate the transmission of two different stations at the same time, one at a higher speed and the other at a lower speed.

Referring now to figure 10, we note that it shows the module main microprocessor and modem interface transceiver. The main microprocessor 149 is a chip type 386 EX with the corresponding statistical and dynamic disk storage, random access (NVR) 150, and multiple electrically erasable programmable permanent memory devices (EEPROM) (not shown), which programming action functions of receiving, transfer, blending and processing of the transceiver. The processor 149 has a respective real-time clock 148.

Via the main bus 205, the processor communicates with the main analog-to-digital Converter 146, with the main peripheral interface 147 and chip 131 high-speed controller signals, which in the existing transceiver is the objects of study were the chip universal serial synchronous controller Silage.

Subject to the receipt and transfer of data are sent over the serial controller 131 to the respective coding-decoding device 128 and 130 and their respective models reinforced MMPS (UMTS) 127 and 129, operating at frequencies of 8 and 80 kilobits per second. In the prototype as modems are modems, UMTS GH. The output from modems 127 and 129 are fed to the interface transmitting unit 206, controlled by the peripheral interface 147 and control circuit power 132. Modems include a synchronization input, which is controlled by the processor, allowing the modems to search for fast capture of signals, and then synchronized, thereby reducing noise, in particular noise coming from the other stations. This property synchronization allows the modem to select the station under control of the controller, which is important for device operation.

Coming from the receiver data available through the interface of the receiving device 207 for modems 127 and 129 and through the coding-decoding device 128 and 120 and the encoder-decoder 128 and 130 on the serial controller 131 for processing by the main processor 149. The broadband and narrowband signals IMLP and signal level meter bursts module of the receiving device are served across the interface 207 to the analog-to-digital Converter 146 for processing by the processor 149.

Consider now 11, there is shown an interface module vocoders. The module contains two vocoder 152 and 153, which are used in the described embodiment, to convert the voice signals into data for transmission between stations in the network. The interface module vocoders essentially converts the voice signal into digital form and then condenses and pattisue" before his passing in schema processor.

In existing transceivers are used vocoders 04400 type Qualcomm. When the audio signals from the microphone 208 are fed through the microphone amplifier 158 to the first and second modules pulse code modulation (PCM) 155 and 156, which selects the audio data and convert them into the format of the PCM. Data PCM fed to the input data of each vocoder and inside are grouped together in 20-millisecond frames (160 PCM samples at 20-millisecond frame). These frames are encoded into packets and displays them on the main processor 149 every 20 milliseconds.

Each package mentioned speech data is transmitted to the processor in a package that is sensitive to frame transmission (TX), which contains data rate for the frame, as well as information binary digits of accuracy. The processor determines the maximum and minimum data transfer rate for the next to be processed 20-millisecond frame. Each package is mentioned data, taken by the processor 149, is formatted for transmission to the latency between receipt of the first sample PCM 20-millisecond frame and the completion of the encoding process for that particular frame, approximately 47.5 in milliseconds. During the time frame of the data processor, the processor reads the binary bit data transfer speeds and range from redundant information before packaging data and output them via the serial controller chip 131.

Because of the flexible work in batch mode transceiver is important to overcome the potential lack of availability of lag in the speed of adaptation of the voice signal, which can lead to loss of transmission capability that occur in the Windows significantly less than 20 milliseconds. That's why there are two parallel vocoder 152 and 153, which provides two (or more, if you use additional vocoders) option to use the main processor 149. For example, the CPU 149 may submit a command to the vocoders to operate at fixed speeds, let's say 4000 and 9600 bits per second, and to select data from each of the vocoder in accordance with the calculated possibility. Thus, the processor has a choice of two different sizes of data packets for transmission on each of the available features of the transmission is. Alternatively, if a single packet is sent at a higher data rate and a successful reception is not performed, the next transmitted packet can enter option of lower speed data of the same frame is transmitted together with the subsequent frame. This provides a way of buffering the transmitted data packets and ensuring effective forms of adjustable speed data transfer, and a feature adaptation of the duration data.

It should be understood that it is possible to use more than two parallel vocoders operating at different data rates, and weekend packages are located in parallel to the buffer device, suitable for flexible transmission. Those packets that are not transmitted because the packet from another vocoder, in this case, simply erased and replaced by subsequent packets.

In addition, various data rates, vocoders can be set with different voice settings, and various delays in coding. Thus, the processor may be installed, for example, one of the vocoders with a low voice tuning and low speed data transmission when installing another on high the voice and high speed data transfer. This scheme can be used for g is renderowania capture the beginning of the speech, and then switch to high speed data transmission with high transmission quality. The use of two vocoders allows you to set one vocoder for demodulation of the data, while the other modulates the data, avoiding, thus, delays in interactive speech, where one vocoder adaptable way switches to read the beginning of the response, while the other still plays the end of the received speech. This device greatly reduces delays, especially in interactive situations.

Received data is sent to one of the vocoders 152 and 153, while the other is suppressed or erased data frames. Repaid frames are also displayed, when accepted destroyed data, to prevent withdrawal of the destroyed data from the vocoder. In these circumstances, the vocoders interpolate or reconstruct missing data. Take the output of their vocoder 152 or 153 is served in the respective module PCM-155 or 156, and the output audio data of a corresponding module selected by the switch analog audio signal 157. The selected audio output signals are sent through the speaker amplifier 159 to the speaker 210.

General adaptive rate vocoders adaptive vary within wide limits due to the long feedback for seconds and adaptable way change within tens of milliseconds based on the selection of superision the x frame data for a number of parallel vocoders. Speech signals are continuously reproduced at all vocoders at the destination station and using a simple analog selection, selects the output voice signal from one of the vocoders. Between the parallel paths of vocoders supported timing through the introduction of teams clearing and erasing those vocoders that did not receive the data packets.

Driven by the voice-off function vocoders is used to recognize when the user speaks. Function decoder typically has priority over the function of encoder. If both users are on both ends of the link say at the same time, usually priority is given to the user at the remote end. The so-called "comfort noise frames and frames above the clearing and erasing are used to fill in the gaps, resulting from packets that are lost during transmission, or packets that are delayed and are taken from the sequence due to mnogovershinnoe line. Accept it can be effectively accelerated by the withdrawal of comfort noise frames and slow through the introduction of the quenching frames, allowing a smooth flow of speech despite varying communication delays.

To network effectively worked using above those is the IR, it is important that passed transmitted data packets to prevent clogging the network of old data. The use of real-time clock 148 allows you to give each transmitted packet relative timestamp, which decreases when the packet passes through the network at a rate that is set relative to real time. Packets that were not successfully received the intended destination station within completing a pre-determined period of time, erased, preventing clogging of the network.

Each station maintains a register of all through her messages, to prevent the following message looping in the network. After passing the particular message through the station, in the future, by means of inspection, reverse return prevents the passage of messages through it a second time and it just redirected to another location. Together with the above timestamp this prevents useless circulation of messages in a circle in the network.

On Fig presents a block diagram illustrating the overall architecture of the software transceiver in the form of a block diagram of the technological process. Block diagram summarizes the above-described operation of the transceiver operating in a network of similar transceivers.

Should underst is th that the above-described variant embodiment of the invention represents only one of many possible embodiments of the invention and it is possible to construct a non-limiting way.
