摘要
The present invention relates to a system (100) and method (600) for modified bit- interleaved coded modulation with iterative decoding (BICM-ID). A first group of coded and interleaved bits (207-1, 207-2, 207-i) is coded with a second. FEC code (208) and a second group of coded and interleaved bits (209-1, 209-n) is not coded with the second FEC code. The first and second groups are then mapped to a modulation format (210). The second FEC code may be a single parity check (SPC) code and the first code may be low-density parity check (LDPC) code. The coding scheme may be referred to as a BICM-ID scheme with fractional secondary coding.
