METHOD OF SOFT COGNITIVE DECODING OF SYSTEMATIC BLOCK CODES Russian patent published in 2018 - IPC H04L1/20 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to network communication technologies. In decoding method, symbols of received code combination V of systematic (n, k)-code are ordered in accordance with basic algorithm in descending order of their soft symbol solutions, and on the basis of performed permutations, vector V' is formed, which together with vector V forms bipartite graph to form permutation matrix P, multiplying by which generator matrix G results in a new matrix G', the first k columns of which are checked for linear independence, and in the case of a positive outcome of this test, matrix G' is reduced to systematic form , the first k most reliable elements of the vector V' by multiplying by form equivalent code V_equiv vector, which in the case of element-by-element addition modulo two with vector V' forms rearranged error vector E', and after multiplying vector E' on P^T error vector E, acting in communication channel by vector V, is formed.

EFFECT: technical result is to increase the decoding rate.
