(57) Abstract:

The proposed transmitter in the mobile communication. In the transmitting device, the encoder receives a stream of information bits in the frame, the length of which celecrity the specified value, and generates the information symbol, the first symbol parity, the second character parity by encoding each information bit. The multiplier sequentially locates information symbols and first and second characters parity row by row in a matrix with integer row and integer columns. The multiplier reorder the columns in the matrix in accordance with a given rule. Further, the interleaver outputs the many radiokatu in the stream by reading characters from top to bottom in each column, starting from the leftmost column to the right. Each radiocat has a specified size. The demultiplexer further demultiplexes each of radiokatu taken from the interleaver, into a stream of information symbols, the flow of the first characters, parity, and flow of the second character parity. Block speed negotiation ignores the stream of information symbols and pierces the flows of first and second characters Kono information on the power and character parity during the encoding of characters in the sending unit. 5 C. and 55 C.p. f-crystals, 31 tab., 19 table.

The technical field to which the invention relates

The present invention relates in General to agreement on the speed channel encoded signal and, in particular, relates to a device and method for controlling a demultiplexer (DEALT) and multiplexer (MULT) used for speed negotiation.

Art

Typically, in wireless systems, such as satellite systems, the system CSCW (digital network integrated services), the system W-mdcr (wideband multiple access and code division multiplexing) system, USMA (universal mobile telecommunication system) and the system MSME-2000 (international mobile telecommunication-2000), before passing the used channel coding source data of the user using the code with error correction, in order to improve system reliability. Typical codes used for channel coding is convolutional codes and linear block code using a single decoder. Recently been proposed turbocode, which is useful for sending and receiving data.

Multi-channel si is istic system matches the number of encoded channel symbols with a given number of data symbols for transmission. This operation is called negotiation speed. To coordinate the transfer rate of the encoded channel symbols widely used puncturing and repetition. Negotiation for speed not so long ago was in USMA important factor to improve the efficiency of data transmission over the air interface and to improve the operating characteristics of the system.

In Fig.1 presents a block diagram of a transmitting device in the uplink communication system for mobile communications (here in USMA).

Please refer to Fig. 1, where the channel encoder 110 receives the data frames at specified time intervals of transmission (VIP), which can be 10, 20, 40 or 80 MS, and encodes the received data frames. Channel encoder 110 generates the encoded symbols in accordance with a given encoding speed R. the Size of the data frame (number of information bits) is defined as (the data rate of the frame)*(VIP). If not to take into account the tail bits, the number of coded symbols is defined as (the size of the data frame)*(velocity encoding R). 1st interleaver 120 performs interleaving of the output signal of the channel encoder 110. Block 130 segmentation radiokatu segments interspersed sqm (the number of encoded characters)/(10), where 10 is the unit of length radicata. Block 140 speed negotiation negotiate speed data radicata received from block 130 segmentation radiokatu, with a given data rate by puncturing or repeating characters radicata. The above components may be provided for each of the services.

MULT 150 multiplexes radically consistent speed from each of the services. Block 160 segmentation of physical channels multiplexed segments radiosity received from MULT 150, the physical blocks of the channels. 2nd interleaver 170 performs interleaving blocks of physical channels received from block 160 segmentation of physical channels. Block 180 allocation of physical channels distributes blocks, past the alternation in the 2nd interleaver, physical channels for transmission.

As shown in Fig.1, the transmitting device uplink communications USMA supplied by blocks 140 speed negotiation. The configuration unit 140 speed negotiation varies depending on whether the channel encoder 110 convolutional encoder, or turbocode.

When used in the channel encoder linear block code (in this case used throughout the world is istic in a multi-channel scheme with multiple access required to have satisfied the following requirements in coordination speed.

1. The input sequence of symbols punctured/repeated in a given periodic combinations.

2. The number of thinned characters is minimized, while the number of repeated symbols is maximized.

3. For the same puncturing/repetition of coded symbols used the same combination of puncturing/repetition.

The above requirements are formulated on the assumption that the sensitivity to the error code of the character at any position in one frame coming from the output of the convolutional encoder, the same. Although the fulfilment of the above requirements can be obtained some positive results when applying turbolader should be used in circuit speed, different from the convolutional encoder, due to the different sensitivity of characters to errors in different places of the same frame.

When using turbocodes preferably, systematic data portion of the coded symbols is punctured, as turbocode is a systematic encoder. Because of the two-component structure is mitsa to the maximum free length of each of the two component codes. To achieve this, the output symbols of the two component encoders must pierce the same, to ensure optimum performance.

As described above, when using turbocodes to achieve optimal coordination of speed in coded symbols should distinguish between information symbols and the symbols of parity. Processing, for example, channel interleaving may be performed between turbocodes and block speed negotiation. However, there must be distinction between the information symbols and the symbols of parity. However, this is impossible, since all the channel encoded symbols after the channel interleave are mixed randomly.

The invention

The present invention is a device and method for performing speed negotiation separately on the information symbols and the symbols of parity during the encoding of characters in the sending device uplink communication system for mobile communications.

Another objective of the present invention is to provide a device and method of placing DEALT before the block matching SLE system for mobile communications.

Another object of the present invention is to provide a device and method of controlling DEALT and MULT when they are used in the reconciliation process speed of the transmitting device uplink communication system for mobile communications.

The next task of the present invention is to provide a device and method of controlling DEALT and MULT when used during speed negotiation signal encoded using turbo code, the transmitting device uplink communication system for mobile communications.

To solve the above and other tasks, a transmitting device in a mobile communication system. In preferred embodiments, the transmitting device, the encoder receives a stream of information bits in the frame, the length of which is integrally divisible by the given size, and generates the information symbol and the first and second symbols of parity, by encoding each information bit. Interleaver consistently has a information symbols and first and second symbols of parity, corresponding to each of the information symbols, line by line in a matrix with multiple rows and multiple columns. As the number of Stolbtsy according to the predetermined rule, reading symbols from top to bottom columns from left to right, and it displays a lot of radiokatu in the stream, and each radiocat size is defined as L/(VIP/10 MS), where L is the number of coded symbols. The demultiplexer further demultiplexes each of radiokatu received from the interleaver, the information symbols, the first symbol parity and second characters parity of radicata. Blocks speed negotiation ignore information symbols and puncture or repeat the first and second characters parity for speed negotiation.

Detailed description of preferred embodiments of the invention

Below with reference to the accompanying drawings, describes preferred embodiments of the present invention. In the following description of known functions or structures are not described in detail so as not to obscure the invention with unnecessary detail.

For speed negotiation transmitting device uplink communications USMA in Fig.1 is a block 140 speed negotiation, the structure of which depends on whether you are using as a channel encoder 110 convolutional encoder, or turbocode, as mentioned above. When used as a channel encoder 110 turbolader according to preferred variants of the present invention in a block 140 speed negotiation include DEALT 141, component (composite) blocks 142, 143 and 144 speed negotiation and MULT 145, as shown in Fig.2. DEALT 141 splits the characters block 130 segmental component blocks 142, 143 and 144 speed negotiation. MULT 145 multiplexes the symbols received from component units 142, 143 and 144 speed negotiation and delivers the multiplexed symbols in the CARTOON 150 in Fig.1.

The transmitting device uplink connection in Fig.2 is constructed in such a way that systematic information symbols from the number of coded symbols is punctured on the assumption that the turbo code is a systematic code. Preferably, two component encoders connected in turbocore in parallel and that the minimum clear distance between the end code provided maximum free distance for each component encoder. The fact that the best performance can be achieved through the same perforation of the output symbols of the two-component encoder included in the structure of the transmitting device ascending line in Fig.2.

According to preferred variants of implementation of the present invention DEALT 141 is located between the block 130 segmentation radiokatu and component units of the speed negotiation 142, 143 and 144, while MULT 145 is located between the component blocks 142, 143 and 144 speed negotiation and th invention, it is shown in Fig.2, DEALT 141 and MULT 145 synchronized with each other so that DEALT 141 and MULT 145 are connected to the same unit speed negotiation (that is, if DEALT 141 is connected to the block 142 speed negotiation to enter a symbol in DEMULT 141, then MULT also connects to the block 142 speed negotiation after the text had been agreed by the speed to get a consistent speed symbol).

The turbo code used in turbocore 110 in Fig.2 is a systematic code and, therefore, can be divided into systematic information symbol Xkand symbols parity Ykand Zk. For turbolader 110 the rate of the code R=1/3. Further systematic information symbol will be denoted by the letter x, the first character parity with the letter u, and the second symbols parity with the letter z. When R=1/3 the relationship between input and output turbolader 110 shown in Fig.3.

Please refer to Fig.3, in which the output signal of turbolader represents the sequence of information symbols x1, the first character parity y1the second character parity z2the information symbol x3, the first character parity y3the second character parity z3,... in that order.

1st interleaver 120 performs interleaving the encoded symbols at time intervals of transmission (VIP) in accordance with the number of characters entered. Interleaving can be divided into two stages.

The first stage

1. The total number of columns is determined by reference to a table. 1, shown below.

2. The minimum integer R1is found from the expression specified in the form

,

where R1- the number of rows; K1- the length of the entered unit (total number of coded symbols) and C1- the number of columns and number of columns C1is 1, 2, 4 or 8 in accordance with the VIP.

3. Input characters on the 1st of interleaver are sequentially by rows in a rectangular matrix having a1rows and C1columns.

The second stage

1. The columns are reordered in accordance with a combination {P1(j)} (j= 0,l,...,C-l) permutation of the columns shown in the table. 1. P1(j) is the original column of the j-th rearranged column, and combines the new sequence each number, for example, 00-->00, 01-->10, 10-->01 and 11-->11, as shown in the row VIP=40 MS in the table. 1.

2. The output signal 1 of the interleaver is a sequence resulting from the reading of the rotated matrix R1C1in columns. The bits that are missing in the input signal 1 of the interleaver, are eliminated in the output by removing the I1defined as

I1=R1C1-K1. (2)

By alternation using equations (1) and (2), 1st interleaver 120 generates alternating symbols in combination similar to the combination of the output signal of turbolader, i.e. combinations of x, y, z, x, y, z,... (or x, z, y, x, z, y,... with characters parity z and y positions are reversed).

When VIP equal to 10 MS, number of columns, C1equal to 1. Therefore, the input signal is 1 of the interleaver and the output signal of the 1 interleaver identical.

In Fig. 4 shows an example of the input signal 1 interleaver after coding using turbo code 160 input bits with R=1/3 and VIP=80 MS. In Fig.4 white rectangle indicates the system information symbol x, the rectangle is shaded by oblique lines indicates the first character parity Ital 120 sequentially receives the code symbols 1, 2, 3, 4, 5, 6, 7, 8, 9, 10...160 from turbolader 110. Each number represents the order of the encoded symbols received from turbolader 110. These numbers also indicate the order in which each of the numbers was received by the interleaver 120 (i.e., first interleaver 120 received '1', then received a '2', and so on). Due to the nature of the turbo code input 1 of the interleaver corresponds to the combination of x, y, z, x, y, z, x, y, z,...

In Fig.5A shows an example of the output signal 1 of the interleaver with R=1/3 and VIP= 20 MS. Please refer to Fig.5A, where the output sequence of the 1st of the interleaver is 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,..., 160 in peremejayutsya order in the combination x, z, y, x, z, y, x, z, y,....

In Fig.5C shows an example of the output signal 1 of the interleaver with R=1/3 and VIP= 80 MS. Please refer to Fig.5C, where the output sequence of the 1st of the interleaver is 1, 9, 17, 25, 33, 41, 49, 57, 65,..., 160 in peremejayutsya order in the combination x, z, y, x, z, y, x, z, y,....

In Fig. 6 shows the use of the VIP= 10 MS input 1 of the interleaver is identical to the output signal 1 of the interleaver. In Fig.6 white rectangle indicates the system information symbol x, and darkened dots rectangle is the symbol of parity.

In Fig. 6 1st interleaver 120 sequentially receives the encoded symbols 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,..., 160 from turbolader 110. Each number represents the order of the encoded symbols received from turbolader 110. Due to the nature of the turbo code output signal 1 of the interleaver should combinations of x, y, x, y, x, y,....

In Fig.7A shows an example of the output signal 1 of the interleaver with R=1/2 and VIP= 20 MS. Please refer to Fig.7A, where the output sequence of the 1st of the interleaver is a 1, 3, 5, 7, 9, 11, 13, 15, 17, 19,..., 159, 2, 4, 6, 8,..., 160 in peremejayutsya order. The first half{1, 3, 5,..., 159} the output signal of the interleaver is an information symbol x, and the second half{2, 4, 6,..., 160} - symbols of parity. That is, the output signal 1 of the interleaver for information symbols follow the characters parity.

In Fig.7B shows an example of the output signal 1 of the interleaver with R=1/2 and VIP= 40 MS. Please refer to Fig.7B, where the output sequence of the 1st of the interleaver is 1, 5, 9, 13,.... 155, 159, 2, 6, 10, 14,..., 156� information symbols x, and the second half{2, 6, 10, 14,..., 156, 160} - symbols of parity. That is, the output signal 1 of the interleaver for information symbols follow the characters parity.

In Fig.7C shows an example of the output signal 1 of the interleaver with R=1/2 and VIP= 80 MS. Please refer to Fig.7C, where the output sequence of the 1st of the interleaver is 1, 9, 11, 17, 25,..., 127, 135, 143, 151, 159, 2, 10, 18, . ..,144, 152, 160 in peremejayutsya order. The first half{1, 9, 17, 25,...,143, 151, 159} the output signal of the interleaver is an information symbol x, and the second half{2, 10, 18,..., 144, 152, 160} - symbols of parity. That is, the output signal 1 of the interleaver for information symbols follow the characters parity.

The output signal of the interleaver shown in Fig. 5A, 5B and 5C, presents under the assumption that the size of the interleaver (=160) integrally divisible VIP/10 MS (= 1, 2, 4 or 8). In the case when the size of the interleaver is not integral multiple of the VIP/10 MS, generates another output signal 1 of the interleaver.

Block 130 segmentation radiokatu in Fig.2 segmenting a frame duration of 10, 20, 40 or 80 MS in blocks radiokatu duration of 10 MS. Since the ratio (L/T) of the size of the input frame (L) to the VIP (T=VIP/the structure (3) for payment L/T fill bits (L is measured by the number of bits or symbols). Here T{1, 2, 4, 8}. If the size of the input frame (the number of encoded characters) of the first interleaver integrally divisible VIP/10 MS, the fill bit is not needed (r=0). If the VIP is 20 MS, and the size of the input frame is not integrally divisible by 2 (VIP/10 MS), the number of fill bits r will be 1. If the VIP is equal to 40 MS, and the size of the input frame is not integrally divisible by 4, the number of fill bits r can range from 1 to 3. If the VIP is set to 80 MS, and the size of the input frame is not integrally divisible by 8, the number of fill bits may be from 1 to 7. The value (L+r)/T, depending on the resulting bit is defined as R (number of rows):

r=T-(L mod T). (3)

where r(0, 1, 2, 3,... T-1}.

R1=(L1+r1)/T1. (4)

If g is not equal to 0, then block 130 segmentation radiokatu inserts a fill bit in the last bit position of the corresponding frame of (T-r+1)-th radicata, in order to keep the size of radicata R. the Value of fill bits is chosen arbitrarily: 0 or 1. Next bit is described, the operation unit 130 segmentation radiokatu.

When describing the bits before they are processed in block 130 segmentation radiokatu it is assumed that the number of fill bits r has already been computed. Here t represents the index racionero of radicata. Each radiocat has the same dimension (L+r)/T. it is Assumed that the output signal 1 of the interleaver is equal to b1b2, ..., bLT(= VIP/10 MS){ 1, 2, 4, 8}, and output the character block segmentation radiokatu represent1with2,...,(L+r)/t in the frame duration of 10 MS.

In order to use the component blocks 142, 143 and 144 speed negotiation in Fig.2 is a more effective transfer of data and improve system performance in a multi-channel system with multiple access by using the above-described mechanism of channel coding. Speed matching refers to the management relationship between the number of input bits to the number of output bits through perforations in the case when the input size is greater than the output size, and repetition in the case when the input size is less than the output size. Puncturing or repetition of characters is usually performed periodically, but the following should be taken into account when negotiating speed when using a turbo code.

1. Since the turbo code is a systematic code, the puncturing part of the coded symbols to the information symbols, should be excluded is kimalee distance for each component encoder, since the two component encoders are connected in turbocore in parallel, determining the turbo code. Therefore, the output symbols of the two component encoders must pierce equally for optimum performance.

In the structure of the speed negotiation shown in Fig.2, speed matching is implemented separately for each component unit of the speed negotiation. First, second and third component blocks 142, 143 and 144 speed negotiation renegotiate speed for an information symbol x, the first character parity and the second character parity z, respectively. In accordance with the specified input and output sizes of each block speed negotiation performs puncturing/repetition for a given number of characters. This structure of the speed negotiation is based on the assumption that DEALT 141 generates x, y, z separately. Therefore, DEALT 141 should be able

split radiocat received from block 130 segmentation radiokatu, the symbols x, y, z in a certain order.

The following describes the output combination radiokatu from block 130 segmentation radiokatu. Radiosity read Kombinacija to block 130 segmentation radiokatu with R=1/3 and VIP=10 MS. Please refer to Fig.8A, where the combination of the output radiokatu identical combinations of input radiokatu, that is, x, y, z, x, y, z,....

In Fig.8B shows the output combination unit 130 segmentation radiokatu when the rate of the code R=1/3 and VIP=20 MS. Please refer to Fig.8B, in which the first radiocat RK 1 is shown in combination x, z, y, x, z, y,..., and the second radiocat RK 2 is shown in combination radicata..., x, y, x, z, y, x, z,... . This weekend combinations correspond to the output signal from the 1st of the interleaver shown in Fig.5A.

In Fig.8C shows the output combination unit 130 segmentation radiokatu with R=1/3 and VIP=40 MS. Please refer to Fig.8C, in which the first radiocat PK l is shown in combination..., x, y, z, x, y, z,..., the second radiocat RK 2 is shown in combination radicata..., z, x, y, z, x, y,..., third radiocat PK 3 in combination..., y, z, x, y, z, x,..., and the fourth radiocat RK 4 in combination. . . , x, y, z, x, y, z,.... This weekend combinations correspond to the output signal from the 1st of the interleaver shown in Fig.5V.

In Fig. 8D shows the output combination unit 130 segmentation radiokatu with R=1/3 and VIP=80 MS. Please refer to Fig.8D, in which the first radiocat RK 1 is shown in combination...,x, z, y, x, z, y,..., the second radiocat ukadr RK 4 in combination. ..,x, z, y, x, z, y,..., fifth radiocat RK 5 in combination..., y, x, z, y, x, z,..., sixth radiocat RK 6 in combination.... z, y, x, z, y, x, seventh radiocat RK 7 in combination..., x, z, y, x, z, y,... and the eighth radiocat RK 8 in combination..., y, x, z, y, x, z,.... This weekend combinations correspond to the output signal from the 1st of the interleaver shown in Fig.5S.

The output combination unit 130 segmentation radiokatu have a certain regularity. Each combination of radicata with the same VIP has a different initial character x, y or z, but the same combination of characters repeat. For VIP= 10 MS and 40 MS, the symbols are repeated in combination..., x, y, z, x, y, z, ..., and for VIP=20 MS and 80 MS, the symbols are repeated in the combination x, z, y, x, z, y,....

In the above cases radiosity not contain a fill bit. The reason for this is that the input size is integrally divisible by VIP/10 MS. If necessary, insert fill bits radiometry have a combination that is different from the above. Below describes the options from the first to the fourth, in which you insert fill bits.

The first option

In Fig. 9A, 9B and 9C shows an input signal 1 of the interleaver, the output signal 1 of the interleaver and the output signal of block segment signal 1 of the interleaver 120 for VIP=80 MS is defined as, it is shown in Fig.9A, it is punctuated by columns in accordance with the rule of alternation for the 1st of the interleaver 120, as shown in Fig.9B. Then characters are read down each column from left to right in the matrix of Fig. 9B. The resulting output signal 1 of the interleaver (i.e., the input signal of the block segmentation radiokatu) will represent the x, z, y, x, z, y, x, z, y, z, y, x, z, y, x, z, y, x, y, x, z, y, x, z, y, x, z, x, z, y, x, z, y, x, z, y. The output signal of block 130 segmentation radiokatu is obtained by adding fill bits to the input signal of the block segmentation radiokatu.

In the first embodiment, the fill bits are set to 0. In the first embodiment of the present invention, the block 130 segmentation radiokatu displays characters received from the interleaver 120, so that all filler bits are placed at the end of the last line, as shown in Fig.9C. In Fig.9B the last position in the second, fourth, sixth and eighth columns blank. Instead take these positions fill bits to fill empty positions, use the following symbol, reaching for the empty position. For example, to fill the last position in the second column of the character 'z' from the first position in Tretiakova 'y', which comes after 'z' in the third column. Mainly the positions of the symbols have been shifted up one position. This process is repeated to fill the empty positions in the fourth column, and so on, However, the last position in the last four columns (i.e. columns 5, 6, 7 and 8) are filled with filling bits so that the fill bits are shifted to the end of the last line, as shown in Fig.9C. The symbols in the matrix of Fig.9C is read from column to column, and each column represents one radiocat. As shown in Fig.9C, each radiocat is different from other primary character, but it has the same combination of repetition symbols x, z, y, in addition to the frames 4 and 6 because of the shift positions. However, in table. 15 shows a combination of repetition, which can be used for radiokatu 4 and 6. The combination of repetition in radiokatu follow the specified combinations of repetition, shown in the table. 15, except for the tails of some radiokatu. In these cases, these tails are ignored and treated as if these tails followed the specified combinations of repetition, shown in the table. 15, and for them is negotiated rate in accordance with predetermined combinations of repetition. The EU is Yes fill bits are missing.

Despite the insertion of fill bits, radiosity can have the same starting characters, and that in the absence of filler bits. The following describes an example of such a case in which there are three fill bits for VIP = 40 MS.

In Fig. 10A and 10B shows an input signal 1 of the interleaver, the output signal 1 of the interleaver and the output signal of the block segmentation radiokatu according to the first variant.

If the input signal is 1 of the interleaver 120 for VIP=40 MS is set, as shown in Fig.10A, it is punctuated by columns in accordance with the rule of alternation for the 1st of the interleaver 120, as shown in Fig.10V. The resulting output signal 1 of the interleaver (i.e., the input signal of the block segmentation radiokatu) represents the x, y, z, x, y, z, z, x, y, z, x, y, z, x, y, z, x, y, z, x, y. The output signal of block 130 segmentation radiokatu shown in Fig.10C, is obtained by adding fill bits in the input signal of the block segmentation radiokatu.

Fill bits are set to 0. The symbols in the matrix of Fig.10C is read in columns, where each column represents one radiocat. As shown in Fig.10C, each radiocat is different from other primary character, but it is one and toxic bits the same initial characters in the absence of filler characters.

The initial character of each radicata is determined by the VIP and the amount of fill bits added by the block 130 segmentation radiokatu. Below describes the starting characters for all possible cases. In table. 3 - 6 describes the starting characters for VIP = 10, 20,40 and 80 MS, respectively, when the block 130 segmentation radiokatu consistently displays radiosity RK 1, RK 2, RC 3, RC 4, RC 5, RC 6, RC 7 and RC 8.

In table. 4, since the 1st interleaver 120 leaves columns unchanged, the position does not change when you use one filling bit. Therefore, the initial characters will be the same as in the absence of filler bits.

When using one or three fill-bits, the number of characters in each column before interleaving is equal to the number of characters in the column with the same index after alternation. Therefore, the initial characters will be the same as the characters in the absence of filler bits. When using two fill bits the number of characters in each column before alternation is different from the number of characters in the column with the same index after alternation. Therefore, the initial symbols differ unausa bits the number of characters in each column before interleaving is equal to the number of characters in the column with the same index after alternation. Therefore, the initial characters will be the same as in the absence of filler bits. When using two, three, four, five or six of fill bits the number of characters in each column before alternation is different from the number of characters in the column with the same index after alternation. Therefore, the initial symbols are different from the initial character in the absence of filler characters.

As can be seen from the above tables, the symbols are repeated in the combination x, y, z, x, y, z, for VIP = 10 MS and 40 MS, whereas VIP = 20 and 80 MS, the symbols are repeated in the combination x, z, y, x, z, y.

Therefore, when this VIP and the amount of fill bits inserted by block 130 segmentation radiokatu, DEALT 141 further demultiplexes the output signal 1 of the interleaver as described above.

The second option

In Fig. 11A - 11D shows an input signal 1 of the interleaver, the output signal 1 of the interleaver and the output signal of the block segmentation radiokatu according to the second variant of implementation of the present invention. The second variant differs from the first variant the fact that the fill bits are inserted 1st interleaver 120 instead of block 130 segmentation radiokatu. Instead of shifting osili fill bits as shown in Fig. 9C. From the point of view of initial symbols and combinations of repetition this case coincides with the usual case where there is no fill bits.

If the input signal is 1 of the interleaver 120 for VIP=80 MS is set as in Fig. 11A, it is punctuated by columns in accordance with the rule of alternation 1 of the interleaver 120, as shown in Fig.11. Then the matrix 11B are inserted filling bits, as shown in Fig.11S. Here fill bits have the value 0. Therefore, the output signal 1 of the interleaver, i.e., the input signal of the block segmentation radiokatu, is a sequence x, z, y, x, z, y, z, y, 0, z, y, x, z, y, x, z, y, x, 0, y, x, z, y, x, z, y, x, z, 0, x, z, y, x, z, y, x, z, y, 0. The output signal of block 130 segmentation radiokatu shown in Fig.11D.

The symbols in the matrix of Fig.11D are read down the columns from left to right, each column represents radiocat. As shown in Fig.11D, each radiocat should be one and the same combination of repetition x, z, y with different initial symbol. As can be seen from Fig. 11A - 11D, the initial symbols are the same as the initial characters in the normal case, in the absence of filler bits.

The initial character of each radicata is determined by the interval VIP. s consistently produces radically RK 1, RK 2, RC 3, RC 4, RC 5, RC 6, RC 7 and RC 8. Starting characters in radiokatu in the second embodiment do not depend on the total number of fill-bits, as shown below; however, in the first embodiment, the initial characters radiokatu depend on the total number of fill bits.

As can be seen from the above tables, the symbols are repeated in the combination x, y, z, x, y, z for VIP=10 MS and 40 MS, whereas for VIP=20 MS and 80 MS, the symbols are repeated in the combination x, z, y, x, z, y.

Therefore, when this VIP DEALT 141 further demultiplexes the output signal 1 of the interleaver as described above.

A third option

In Fig. 12A, 12B and 12C shows an input signal 1 of the interleaver, the output signal 1 of the interleaver and the output signal of the block segmentation radiokatu according to the third variant of implementation of the present invention. A third option is different from the second option the fact that the controller (host computer) denotes the position to insert fill bits, and the block 130 segmentation radiokatu insert fill bits in the indicated position. From the point of view of initial symbols and combinations of repetition this case coincides with the usual case where there is no fill bits.

If the input signal 1-Emesene 1st interleaver 120, as shown in Fig.12V. Therefore, the output signal 1 of the interleaver, i.e., the input signal of the block segmentation radiokatu, is a sequence x, z, y, x, z, y, x, z, y, z, y, x, z, y, x, z, y, x, y, x, z, y, x, z, y, x, z, x, z, y, x, z, y, x, z, y. Controller (host computer) denotes the position to insert fill bits, and then block 130 segmentation radiokatu insert fill bits in the indicated position, as shown in Fig.12C.

In this embodiment, the fill bits are set to 0. The symbols in the matrix of Fig. 12C are read down the columns from left to right, each column represents radiocat. As shown in Fig.12C, each radiocat should be one and the same combination of repetition x, z, y with different initial symbol. As can be seen from Fig. 12A, 12B and 12C, the initial symbols are the same as the initial characters in the normal case, in the absence of filler bits.

The initial character of each radicata is determined by the interval VIP. In table. 11 - 14 shows the initial characters for VIP=10, 20, 40 and 80 MS, respectively, when the block 130 segmentation radiokatu consistently produces radically RK 1, RK 2, RC 3, RC 4, RC 5, RC 6, RC 7 and RC 8. Starting characters in radiokatu in the third embodiment does not depend on the General colic combinations of x, y, z, x, y, z for VIP=10 MS and 40 MS, whereas for VIP=20 MS and 80 MS, the symbols are repeated in the combination x, z, y, x, z, y.

When this VIP DEALT 141 further demultiplexes the output signal 1 of the interleaver as described above.

Please refer to Fig.2, where DEALT 141 demuxes radiocat obtained from block 130 segmentation radiokatu, the symbols x, y, z in accordance with rule switching. Rule switching is determined by the VIP and the amount of fill bits used by the block 130 segmentation radiokatu in the first embodiment, and VIP in the second and third options. The characters are repeated in a certain combination. The combination of repetition for these options is shown in table. 15 and 16. In these tables, N/A means "not applicable".

If VIP=40 MS in the first and second embodiments, there are two fill-bits, the combination of commutation in DEMULT 141 represent the x, y, z, x, z, y, z for the first radicata, z, x, y, z, x, y for the second radicata, z, x, y, z, x, y for the third radicata and x, y, z, x, y, z for the fourth radicata.

The second and third options, you only need to specify the initial character of each radicata, because the combination of repetition of already determined in advance based on the VIP. information. From table. 17-19 shows the distinction between the variants.

Refer again to Fig.2, where MULT 145 multiplexes three streams received from component units 142, 143 and 144 speed negotiation, in one stream, thereby generating a consistent speed radiocat with the same combination of characters as up to speed negotiation. Because this CARTOON 145 is equivalent to DEALT 141, he commutes symbols in accordance with the same combinations of commutation.

In Fig.13 presents a block diagram of the control device of DEMULT and MULT according to the first variant implementation of the present invention.

Please refer to Fig.13, where after taking the VIP, the total number of fill-bits, and the length of radicata from the host computer 200, the controller 210 sends a VIP, the total number of fill-bits, and the index of the current radicata in the memory 220 (see tab. 17) and receives from the memory 220, the initial symbol of the current radicata. The controller 210 controls the operations of switching DEALT 141 and MULT 145 based on the starting character and the combination of repetition/puncturing determined VIP. DEALT 141 distributes the symbols of the current radicata to corresponding inputs of component matching units before 141 allocates information symbol, the first character parity and the second character parity of flow radiokatu obtained from block 130 segmentation radiokatu. Component units 142, 143 and 144 speed negotiation agree on the speed information of the character, the first character parity and the second character parity from DEALT 141, respectively, by puncturing or repetition. Component unit 142 speed negotiation simply ignores the received information symbols without perforations, while the blocks 143 and 144 speed negotiation pierce received symbols parity in accordance with a given combination, which is determined by the ratio of the number of input symbols to the number of output symbols. In most real cases, the component blocks 143 and 144 speed negotiation simply ignore the received symbols parity, in fact, not repeating them, except the occasional repetition of encoded symbols, whereas the component unit 142 speed negotiation repeats the received information symbols in accordance with a given combination, determined by the ratio of the number of input symbols to the number of output symbols.

The MULIA is according to the same combination for switching, which is used in DEMULT 141.

In Fig.14 presents a block diagram of the control device of DEMULT and MULT according to the second variant of implementation of the present invention.

Please refer to Fig. 14, where after taking the VIP and length of radicata from the host computer 200, the controller 210 sends a VIP, the total number of fill-bits, and the index of the current radicata in the memory 220 (see tab. 17) and receives from the memory 220, the initial symbol of the current radicata. The number of fill bits is determined by the controller 210 based on the VIP and the length of the frame in the same manner as in the block segmentation radiokatu. Then, the controller 210 controls the operations of switching DEALT 141 and MULT 145 based on the starting character and the combination of repetition/puncturing determined VIP. DEALT 141 distributes the symbols of the current radicata to the inputs of the component units of the speed negotiation, and MULT 145 multiplexes output characters matching units speed radiocat. Here DEALT 141 selects the information symbol, the first symbol parity and the second character parity of flow radiokatu obtained from block 130 segmentation radiokatu. Component units 142, 143 and 144 reconciliation of kororaa on parity from DEALT 141, respectively, by puncturing or repetition. Component unit 142 speed negotiation simply ignores the received information symbols without perforations, while the blocks 143 and 144 speed negotiation pierce received symbols parity in accordance with a given combination, which is determined by the ratio of the number of input symbols to the number of output symbols. In most real cases, the component blocks 143 and 144 speed negotiation simply ignore the received symbols parity, in fact, not repeating them, except the occasional repetition of encoded symbols, whereas the component unit 142 speed negotiation repeats the received information symbols in accordance with a given combination, determined by the ratio of the number of input symbols to the number of output symbols. MULT 145 multiplexes the symbols received from component units 142, 143 and 144 speed negotiation, in one thread according to the same combination for switching, which is used in DEMULT 141.

In Fig.15 presents a block diagram of the control device of DEMULT and MULT according to the third variant of implementation of the present invention.

Please refer to Fig. 15, where, after receiving the memory 220 (see table. 18) and receives from the memory 220, the initial symbol of the current radicata. Then, the controller 210 controls the operations of switching DEALT 141 and MULT 145 based on the starting character and the combination of repetition/puncturing determined VIP. DEALT 141 distributes the symbols of the current radicata to the inputs of the component units of the speed negotiation, and MULT 145 multiplexes output characters matching units speed radiocat. Here DEALT 141 selects the information symbol, the first symbol parity and the second character parity of flow radiokatu obtained from block 130 segmentation radiokatu. Component units 142, 143 and 144 speed negotiation agree on the speed information of the character, the first character parity and the second character parity from DEALT 141, respectively, by puncturing or repetition. Component unit 142 speed negotiation simply ignores the received information symbols in fact, without perforations, while the blocks 143 and 144 speed negotiation puncture or repeat the received symbols parity in accordance with a given combination, which is determined by the ratio of the number of input characters to colistin in one thread in accordance with the same combination for switching, what is used in DEMULT 141. In most real cases, the component blocks 143 and 144 speed negotiation simply ignore the received symbols parity, in fact, not repeating them, except the occasional repetition of encoded symbols, whereas the component unit 142 speed negotiation repeats the received information symbols in accordance with a given combination, determined by the ratio of the number of input symbols to the number of output symbols.

As described above, an advantage of the present invention is that it is possible to perform effective negotiation speed, when DEALT before the unit speed negotiation for separation information symbol and symbols of parity in the encoded character information when the character does not have to pierce for speed negotiation in the transmitter uplink communications in a mobile telecommunications system.

FIELD: communication technologies.

SUBSTANCE: detecting techniques for close components of multi-beam distribution are described. The techniques are aimed at prevention of channel merging without relative position monitoring between each of diversity channel set. Displacement limits are defined for each diversity channel. Temporary tracing commands are suppressed. Such commands may displace diversity channels beyond their displacement limits. Displacement limits are dynamically updated, with displacement limits for each diversity channel defined according to displacement limits of adjacent diversity channels.

EFFECT: prevention of diversity channel merging; increase in system efficiency and capacity and decreased improper use of system resources.
