摘要
Provided are a signaling coding and modulation method and a demodulation and decoding method and device, characterized in that the method comprises the steps of: extending signaling which has been subjected to first predetermined processing according to an extension pattern table to obtain an extended codeword, and conducting predetermined coding on the extended codeword to obtain a encoded codeword; conducting parity bit permutation on a parity bit portion in the encoded codeword and then splicing the permutated parity bits to the end of information bits in the encoded codeword, to obtain a permutated encoded codeword; according to the length of the signaling, punching the permutated encoded codeword according to a predetermined punching rule to obtain a punched encoded codeword; and conducting second predetermined processing on the punched encoded codeword to obtain a tuple sequence, which is used for mapping, and then mapping the tuple sequence.
