FIELD: communication.
SUBSTANCE: method includes encoding of an input bit sequence using a low-density parity check (hereinafter – LDPC) code matrix, where LDPC matrix is obtained based on a lifting coefficient Z and a base matrix. The base matrix includes rows from 0 to row 4 and column 0 in column 26 in one of matrices, or the base matrix includes rows from 0 to row 4 and some of columns from 0 to column 26 in one of matrices.
EFFECT: increase in the reliability of channel transmission and effective power use in LDPC communication system.
