METHOD AND APPARATUS FOR CHANNEL ENCODING AND DECODING IN COMMUNICATION SYSTEM USING LOW-DENSITY PARITY-CHECK CODES Russian patent published in 2013 - IPC H04H60/88 

FIELD: radio engineering, communication.

SUBSTANCE: method for channel encoding in a communication system using low-density parity check codes (LDPC) includes steps of dividing information bits into a plurality of bit groups; determining the number of information bits that should be cut; determining the number of bit groups that should be cut; cutting information bits in a defined number of bit groups according to a given order based on the determined number of information bits that should be cut; performing LDPC encoding of the cut information bits.

EFFECT: efficient support of different lengths of code words from an existing parity check matrix without the need to construct a new parity check matrix.
