METHOD AND APPARATUS FOR CHANNEL ENCODING AND DECODING IN COMMUNICATION SYSTEM USING LOW-DENSITY PARITY CHECK CODES Russian patent published in 2014 - IPC H03M13/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to a communication system which employs low-density parity check (LDPC) codes. The method for channel decoding using a LDPC code includes a step of demodulating a signal transmitted from a transmitter. The method also includes a step of determining positions of punctured parity bits by evaluating information on a predetermined order of sets of parity bits to be punctured and the number of sets of parity bits. Further, data are decoded using said positions of punctured parity bits.

EFFECT: high efficiency of channel encoding/decoding using LDPC codes.
