Abstract:
An interleaving and mapping method and a deinterleaving and demapping method for an LDPC codeword are provided. The interleaving and mapping method comprises: performing first bit interleaving on a parity bits part of the LDPC codeword to obtain interleaved parity bits; splicing an information bit part of the codeword and the interleaved parity bits into a codeword after the first bit interleaving; dividing the codeword after the first bit interleaving into multiple consecutive bit subblocks in a predetermined length, and changing the order of the bit subblocks according to a corresponding permutation order (bit-swapping pattern) to form a codeword after second bit interleaving; dividing the codeword after the second bit interleaving into two parts, and writing the two parts into storage space in a column order respectively and reading the two parts from the storage space in a row order respectively to obtain a codeword after third bit interleaving.

Claim (Index 17):
A constellation mapping method, comprising:\n performing, according to a corresponding constellation diagram, constellation mapping on an LDPC codeword which is bit interleaved according to a bit interleaving pattern, wherein for LDPC codewords with different code lengths, code rates and LDPC code matrices tables, such that the capacity of bit interleaved coding and modulation is maximized, matched constellation diagrams and bit interleaving patterns are designed by means of theoretical analysis and optimization.
