MODULATION FORMAT SPECIFIC PUNCTURING PATTERN FOR LDPC CODES IN COMBINATION WITH 16QAM AND 64QAM

摘要

A method and apparatus for channel encoding and decoding in a communication system using punctured Low-Density Parity-Check (LDPC) code is provided. The puncturing pattern depends on the modulation scheme and is based on puncturing of parity bit sets that reflect the properties of the LDPC codes, which are preferably LDPC codes as defined in the context of the DVB-S2 specification.
