FIELD: information technology.
SUBSTANCE: in the method, the number of parity bits subject to deletion is determined; the parity bits are divided into predetermined intervals and the number of deleted bits, which are subject to deletion in these predetermined intervals, is determined; positions of the deleted parity bits corresponding to the specified number of deleted bits are determined; deletion is repeatedly applied to said deleted parity bits corresponding to said determined positions in said predetermined intervals. Said predetermined intervals are defined by dividing the length of parity bits into a length of one group of columns in a parity check matrix.
EFFECT: optimisation of output of a communication system using low-density parity check codes.
