The technical field The present invention mainly relates to a wireless communication system, which uses the distribution of pilot signals, to method and its pilot model; more specifically the invention relates to a method for allocating a pilot subcarrier for multiple pilot data streams antennas system with many inputs and outputs (MMO)using modulation, known as multiplexing orthogonal frequency division (OFDM). Background of invention Recent research work in the field of wireless communication systems of the next generation is aimed at providing much higher data rates than existing systems. Basically the reference signals or pilot symbols that are typically used in high speed devices and systems for wireless data transmission, are used to set the initial time interval, frequency synchronization, identification of a cell and channel estimation. Evaluation of the channel indicates the process of compensating for distortions that occur due to rapid changes in the surrounding environment when the sinking and recovery of the signal. In the system multiplexing orthogonal frequency division (OFDM), in particular the reference or pilot signal related to the predetermined sequence si the channels, is inserted in a predetermined place in the time interval or frequency domain data stream, and the communication device can detect the reference or pilot signal after receiving the data stream with subsequent synchronization in time and frequency, to measure the information channel and perform the weakening of or interference rejection. A system of antennas, multiple input multiple outputs (MMO), is used to transmit and receive data, increasing the speed and efficiency of the reception. In the system MMO signal passes through the channel corresponding to each antenna. A large number of antennas requires more reference or pilot signals, but the "allowance" on the placement of the pilot signals is more official channels and reduces the number of channels for data transmission. Serious loss of pilot signals and the speed reduction gear. Accordingly, it is necessary to organize the distribution of pilot signals, taking into account the presence of multiple antennas. In the prior art have been developed and used different patterns of distribution of pilot signals, for example in the system e Institute of electrical and electronics engineers (IEEE) pilot signals are separated from each other in the time interval. However, although there were considered several schemes pilot structure is R, currently there is a lack of systematic approach to the design of pilot structures or templates that are used in systems antennas with multiple inputs-outputs (MIMO), using multiplexing orthogonal frequency division (OFDM). SUMMARY of INVENTION The aim of the present invention is to provide a method for efficient distribution of pilot signals for transmission to multiple pilot flow, increase the speed of transmission antennas system with many inputs-outputs (MIMO), using multiplexing orthogonal frequency division (OFDM). The purpose of the present invention can be achieved by creating a method of allocating pilot signals for transmission to multiple pilot flow through the system of MIMO antennas using modulation, known as multiplexing orthogonal frequency division (OFDM), the method comprises the following stage. There are two patterns of adjacent frames, and each frame includes OFDM symbols in the time interval and subcarriers in frequency domain. In the structure of one frame are two of the pilot signal for each of the pilot flow. Then the pilot signals in the pilot stream are placed in the structure of the first frame, and pilot signals for pilot stream in the structure of the second frame based on raspredeleniya signals in the first frame structure. The purpose of the present invention can be achieved by providing a method of allocating pilot signals for transmission to multiple pilot flows through the antenna MIMO system using the OFDM modulation, while this method includes the following stages. First, create two patterns of adjacent frames, and each frame structure contains the OFDM symbols in the time interval and subcarriers in frequency domain. Pilot streams are grouped into two clusters of pilot streams. There are two pilot signal in each pilot stream in the structure of one frame and pilot subcarriers for each cluster pilot streams, forming two pilot cluster. The first pilot cluster to the first cluster pilot threads posted in the first part of subcarriers in the first part of the OFDM symbols and the second pilot cluster for the first cluster of the pilot streams allocated in the second part of subcarriers in the second part of the OFDM symbols in the first frame structure. The first pilot cluster to the second cluster pilot threads posted in the first part of subcarriers in the second part of the OFDM symbols and second pilot cluster for the second cluster of pilot streams allocated in the second part of subcarriers in the first part of the OFDM symbols in the first frame structure. The placement of the pilot signals in the structure of the second frame is similar to the placement of the pilot is Ignatov in the structure of the first frame. The second pilot cluster for the second cluster pilot streams in the structure of the first frame and the first pilot cluster to the first cluster pilot streams in the structure of the second frame separated by an even number of subcarriers.

A DETAILED DESCRIPTION of the PREFERRED embodiments In the following detailed description referring to the attached drawings, which are part of the description and illustrate specific embodiments of the invention. Professionals understand that they can be used in other examples of implementation, and what can be done structural,electrical or procedural changes, without leaving the scope of the present invention. Wherever possible, the drawings will be used the same number of positions to indicate the same or similar components and assemblies. The figure 1 presents the block diagram of an exemplary transmitter and receiver according to the present invention. The transmitter 100 includes a data processor 101, the dispenser subcarriers 102 and modulator 103 system multiplexing orthogonal frequency division (OFDM)receiver 120 includes a data processor 121, the evaluation unit of the channel 122 and the OFDM demodulator 123. In a wireless communication network can be used in various systems such as code division channels multiple access (CDMA), wideband multiple access code division multiplexing (WCDMA), wireless local area network (WLAN), worldwide compatible network broadband wireless access (WiMAX), and multiplexing orthogonal frequency division (OFDM), and these systems may include at least a base station and at least one terminal. Terminal based on the signal transmission between the transmitter 100 and receiver 120 receives signals or data from the base station on the downlink (DL), establishes a communication channel between the terminal and the base station and transmits signals or data to the base station through the channel wash is coming due (UL) between the terminal and the base station. The data processor 101 may include various circuitry designed to perform various functions, for example, the data processor 101 may encode the input data 111 by a predetermined encoding method and generating encoded word and then converting the encoded words in the symbol that represents the position of a tone in the group, and processing the input character by the way MIMO using multiple antennas 104. Preferably, the modulation scheme in such a system, based on the data processor 101 would include a diagram of the phase modulation (m-PSK) or quadrature amplitude-shift keying (QAM). The dispenser subcarriers 150 distributes the processed input symbols and pilot signals 112 in the subcarriers. Pilot signals are distributed by the transmitting antenna 104. The pilot signals are received from the transmitter 100 to the receiver 120 and can be used for channel estimation, time and frequency synchronization and error phase shift subcarriers. The pilot signal is also called a reference signal. The OFDM modulator 160 can modulate the input symbol and to generate OFDM symbols. The OFDM modulator 160 may perform a fast inverse Fourier transform (IFFT) on the input symbol and the subsequent insertion of a cyclic prefix (CP) after performing the IFFT. The OFDM symbols are transmitted through the antenna 104. The receiver 120 receives Ignacy with antennas 124, subjected to a fast Fourier transformation (FFT) of the OFDM demodulator 123. Block channel estimation 220 evaluates the use of channels of received pilot signals 112. The data processor 121 may convert the input symbol in the encoded word and then decoding the encoded word and restore the original data. Preferably the data processor 101 and the distributor subcarriers 102 are formed as separate modules or distributor subcarriers 150 and the data processor 101 may be embedded in the processor. Preferably, the evaluation unit of the channel 122 and the data processor 121 are formed as separate modules, or the evaluation unit of the channel 122 and the data processor 121 can be embedded in the processor. The transmitter 100 and the receiver 120 can communicate with each other using the OFDM scheme. Further, the transmitter 100 and the receiver 120 may use a combined pilot symbols or pilot patterns for communication Protocol OFDM. United pilot patterns as they are used here to refer to the same pilot structures used for the common pilot signals, i.e. all users can use specialized pilot signals, i.e. signals that are restricted to specific user or users. United pilot patterns can also refer to the same pilot structures, the use of which has been created for DL transmission, and for UL transmission. Further, the United pilot patterns may relate to the number of pilot signals that are systematically used in various operating modes, such as different number of data streams, various sizes are used resource (RU) and/or various configurations of the base station and the wireless cell. The figure 2 shows an exemplary frame structure in the OFDM scheme. As shown in figure 2, the data transmission OFDM can be represented in time and frequency, where the vertical axis represents frequency and the horizontal axis represents time. Frame structure 200, also called a resource block (RU), include 18 subcarriers (vertical axis)×six OFDM symbols (horizontal axis), in which podcat includes six OFDM symbols. Data OFDM can be transferred to a resource element 201 of the frame structure 200 per subcarrier (frequency band) in time (OFDM symbol). Frame structure 200 can refer to the basic unit for resource allocation that includes a predefined number of contiguous subcarriers on predefined number of contiguous OFDMA symbols. The main unit of the resource - 18 subcarriers and 6 characters (18x6) data block, however, placement of pilot signals according to the present invention is also applicable to other blocks of the resource, for example, the resource block may be a block of data from 18 under sushimi and 5 characters (h) or data block with 18 subcarriers and 7 characters (h), as shown in figure 8. Each symbol (a small rectangle in EN 200) can be used to transmit any type of information. For example, the character data has data and the pilot symbol carries a pilot signal. However, because adding pilot signals can reduce the number of data characters, it can be desirable compromise between adding minimal header to provide a reliable estimate of the channel using pilot symbols, so as not to affect the spectral characteristics and the speed of data transmission. The currency may become more difficult in the MIMO schemes, because it can be used multiple antennas and multiple data streams, or wired and wireless signals can coexist in a specific time and location. Basically throughput η communication line is defined as the following formula in the wireless standard
In the wireless communication system, using a system of antennas 8×8 MIMO, can transmit eight data streams (M=8) at the same time, when the provided bandwidth is 10 MHz (BW=10 MHz), the transmission time podagra is (5×10-3)/8 seconds (TSF=(5×10-3)/8), provided the order of modulation is six (m=6) and the encoding rate of the channel provided for each data stream, equal 237/256 (Rc=237/256), 48 EN are provided for each podagra (NRU, SF=48). Unit RU is a 18 subcarriers and 6 characters (18×6), data block and 3 of the pilot signal in each data stream (NP EN=3×8), the bandwidth of a downlink in such a wireless system is e can be calculated as follows:
If there are two pilot signal in each data stream (NpEN=2x8), the bandwidth of a downlink in such a wireless system is calculated as follows:
Accommodation 3 pilot signals in the data stream reduces the bandwidth required for wireless communication standard, such as standard wireless 4G downlink, to less than 30 bits per second/Hz. When 2 of the pilot signal is used for each data stream in one unit RU, the bandwidth of the downlink transmission can meet the requirement of the wireless standard. To satisfy the requirement of high bandwidth, transmission speed and performance evaluation of channel, two pilot signal is used for each data stream in each of the two structures adjacent frames. Figure 3 is a flow diagram of a method of allocating pilot signals for transmission to multiple pilot flows through the antenna system MMO using the OFDM modulation according to the present invention. The method includes the following stages. At the stage 31 are provided with two patterns of adjacent frames, and each frame structure includes OFDM symbols in the time interval and subcarriers in frequency domain, as the show is but the figure 2. At stage 32 has two pilot signal to each pilot stream, which is placed in the structure of the first frame. For example, when the antenna MIMO system with OFDM modulation is used to transmit 8 data streams simultaneously in one frame structure 16 is introduced pilot signals. At stage 33 two of the pilot signal is provided for each pilot stream, placed in the structure of the second frame, based on the distribution of pilot signals in the first frame structure. For example, the relative location between the pilot signals in the structure of the second frame can be mostly similar with the locations of the pilot signals in the first frame structure. Preferably, if the pilot signals are grouped in several pilot clusters for distribution, the relative locations of pilot clusters in the structure of the second frame may be a copy or mirror the relative locations of pilot clusters in the structure of the first frame. Preferably this method of allocating pilot signals can be performed by a distributor subcarriers 102 shown in figure 1, or processor, is able to allocate the pilot signals. Figure 4 is a flow diagram of an example implementation of a method of allocating pilot signals for transmission to multiple pilot on the shackles through the antenna MIMO system, using the OFDM modulation according to the present invention, and figure 5 illustrates an example set of redundant parts for allocating pilot signals in the structures of adjacent frames in the modulation scheme OFDM. At the stage 41 is provided with two patterns of adjacent frames, and each frame structure includes an OFDM symbol in the time interval and subcarriers in frequency domain, such as the structure of the frame 50 and the frame structure 51 shown in figure 5, where these 6 columns represent the 6 OFDM symbols, and 36 rows represent 36 subcarriers. At stage 42 pilot streams are grouped into two clusters of pilot streams. For example, the pilot stream 1, the pilot stream 2, the pilot stream 5 and a pilot stream 6 are grouped in one cluster pilot flow and the pilot flow 3, the pilot flow 4, the pilot flow 7 and the pilot flow 8 are grouped in another cluster pilot threads. At the stage 43 for each pilot stream in the structure of one frame are provided with two pilot signal and the pilot signals for each cluster pilot streams form the two pilot cluster. For example, pilot signals for pilot stream 1, the pilot stream 2, the pilot flow 5 and the pilot flow 6 form a pilot cluster 531 and a pilot cluster 532, and a pilot signal to the pilot flow 3, the pilot flow 4, the pilot flow 7 and the pilot flow 8 forms the shape of a pilot cluster 533 and pilot cluster 534, as shown in figure 5, where 'G is a pilot model pilot stream 1; '2' represents pilot model pilot stream 2; '3' is a pilot model pilot flow 3; '4' represents pilot model pilot stream 4; '5' represents pilot model pilot flow 5; '6' represents pilot model pilot flow 6; '7' represents pilot model pilot flow 7; '8' represents pilot model pilot flow 8. At stage 44 of the first pilot cluster to the first cluster pilot threads posted in the first part of subcarriers in the first part of the OFDM symbols and second pilot cluster for the first cluster pilot streams in the second part of subcarriers in the second part of the OFDM symbols in the first frame structure. For example, a pilot cluster 531 can be placed in the portion 501 formed by four elements of the resource and pilot cluster 532 can be placed in the section 504 formed by four elements of the resource. At stage 45, the first pilot cluster to the second cluster pilot threads posted in the first part of subcarriers in the second part of the OFDM symbols and second pilot cluster for the second cluster of pilot streams allocated in the second part of subcarriers in the first part of the OFDM symbols in the first frame structure. For example, a pilot cluster 531 can be placed in part 501, and the pilot cluster can be placed in part 502. For example, a pilot cluster 533 may be placed in part 502 formed by four elements of the resource and pilot cluster 534 can be placed in the part 503 formed by four elements of the resource. At stage 46 of the pilot signals are placed in the structure of the second frame based on the distribution of pilot signals in the first frame structure. Preferably, the relative locations of pilot clusters in the structure of the second frame is a copy of the relative locations of pilot clusters in the structure of the first frame. For example, when a pilot cluster for the first cluster pilot threads in the frame structure 50 is placed in sections 501 and 504, the relative locations of pilot clusters in the structure of the frame 51 can be a copy of the relative locations of pilot clusters in the frame structure 50, and this means that the pilot cluster for the first cluster pilot threads in the frame structure 51 can be placed in parts 511 and 514, as shown in figure 5, and the pilot cluster to the second cluster pilot threads in the frame structure 51 can be placed in parts 512 and 513. Preferably, this embodiment of the method of allocating pilot signals could be performed by the distributor subcarriers 102 shown in figure 1, or processor, is able to distribute the pilot signal is Aly. Figure 6 illustrates a diagram of the positioning redundant parts for allocating pilot signals in the structures of adjacent frames in the modulation scheme OFDM. Note that the distance between the pilot clusters, shown in figure 5, can be defined by the following formulas:
For example, the number of subcarriers in the structure of two adjacent frames is equal to 36, still the way Nac,fcan be defined as 35. Because two of the pilot signal is provided for each pilot stream in the structure of one frame, Np,fis defined as 4. According to the formulas (1-2), SF,Scan be defined as 11 The number of units in a short span of SF,Sis defined as 2(NF,S=4 (35 mode 3)=2), and SF,Lis defined as 12(SF,L=11+1=12), NF,Lis defined as 1 (NS,L=(35 mode 3)-1=1).
