An important consideration in a coded modulation scheme is the choice of the component codes, which has a significant impact on the overall bit error rate performance and which determines the decoding complexity. Methods and apparatus employing product codes are described that can improve the performance of selected classes of information in the coded modulation scheme without affecting the decoding complexity or performance of other classes of information.

[ What is claimed is:] [1.] A coded modulation method, comprising the steps of:encoding each of a plurality of streams of data bits according to a respective code, thereby generating respective streams of coded bits, wherein a stream of data bits is encoded according to a product code and at least one other stream of data bits is encoded according to at least one other code, andselecting modulation symbols based on respective groups of the coded bits, wherein each group includes coded bits from all of the streams of coded bits, wherein an inner code of the product code and the at least one other code are block codes, and wherein further the block codes have a same predetermined block length.
