The method of forming an integrated quasiorthogonal code and device and method for extending channel data using quasiorthogonal code in the communication system mdcr

 

The invention relates to the field of radio and can be used in the mobile communication system mdcr for the formation of complex quasiorthogonal codes and to expand channel data using a comprehensive quasiorthogonal codes. The technical result is an increase in throughput of the communication channels in the communication system mdcr. The method includes the formation of a M-sequence of length N, and a special sequence, having a good full correlation with the M-sequence, the formation of a predetermined number of other special sequences by cyclic shift of the M-sequence and permutation of columns cyclically shifted of specific sequences in the same way, and that way permutations of columns to convert the generated M-sequence orthogonal Walsh codes for mask formation candidate, formation samples quasiorthogonal codes by operating with masks candidates and orthogonal Walsh codes having the same length as the mask candidate and the choice quasiorthogonal codes based on samples quasiorthogonal codes and private quasiorthogonal codes. 6 C. and 13 C.p. f-crystals, 22 ill.
