METHOD AND APPARATUS FOR CHANNEL ENCODING AND DECODING IN COMMUNICATION SYSTEM USING LOW-DENSITY PARITY CHECK CODES Russian patent published in 2013 - IPC H03M13/11 

FIELD: radio engineering, communication.

SUBSTANCE: encoding method includes steps where information bits are divided into a plurality of groups of bits. Further, according to the method, the number of information bits to be cut is determined. The number of groups of bits to be cut is then determined based on the determined number of information bits to be cut; information bits are cut in the determined number of groups of bits according to a predetermined sequence, and LDPC coding of the cut information bits is performed.

EFFECT: high efficiency of channel encoding and decoding in a communication system using LDPC codes.
