SIGNALLING CODING AND MODULATION METHOD AND DEMODULATION AND DECODING METHOD AND DEVICE

摘要

The present invention provides a kind of signaling coding modulation method, demodulation decoding method and apparatus, by extending the signaling after the first predetermined processing according to an extension pattern table to obtain an extended codeword, and predetermined coding for the extended codeword A procedure of obtaining a coded codeword by performing a parity bit substitution for the parity bit in the coded codeword, and then joining the parity bit after the substitution to the information bit in the coded codeword to the coded code after substitution A procedure for obtaining a word, a procedure for obtaining a coded codeword after punching by punching the coded codeword after substitution according to a predetermined punching rule according to the length of the signaling, and a first for the coded codeword after punching 2 It includes a procedure of obtaining a tuple sequence used for mapping by performing a predetermined process, and mapping the tuple sequence used for the mapping to a signaling symbol according to a predetermined mapping rule.
