Abstract:
Provided is a bit interleaved coded modulation-iterative decoding (BICM-ID) technique suffering a small loss in a transfer rate. A BICM-ID technique allowing a decoder to treat a small processing quantity is also provided. Encoding is carried out according to a code based on an iterative code. Encoded bits are reordered during interleaving processing, subjected to multi-valued modulation through extended mapping, and then transmitted. The extended mapping includes number-of-bits thinning processing of thinning l bits into m bits (m
