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

摘要

The present invention provides a signaling coding modulation method, a demodulation decoding method, and an apparatus of a kind, which extend signaling after a first predetermined processing according to an extended pattern table to obtain an extended code word, A parity bit replacer for parity bits in the coded codeword, and a parity bit replacer for replacing the parity bit after the replacement with the information bits in the coded codeword to obtain a coded codeword Obtaining a code word, obtaining a code word after punching by punching the coded code word after the substitution according to a predetermined puncturing rule according to the length of the signaling, and obtaining a code word after punching A second predetermined process is performed to obtain a tuple sequence to be used for the mapping, and the tuple sequence to be used for the mapping according to a predetermined mapping rule Includes a procedure for mapping a sequence of tuples in the signaling symbols.
