Method and apparatus for channel encoding in a communication system using low-density parity-check codes

摘要

A method for channel encoding in a communication system using a DVB-S2 Low-Density Parity-Check (LDPC) code; the method comprising reading parity check matrix information; determining a length K 2 , where K 2 denotes a length of information bits to be obtained by shortening, wherein the information bits include 168 BCH parity bits; based on the length K 2 , performing shortening on information bits in an order according to a predetermined shortening pattern defined in a given table.
