Abstract
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.
