Abstract
Systems and methods for improving the performance of iterative decoders on various channels with memory are disclosed. These systems and methods may reduce the frequency or number of situations in which the iterative decoder cannot produce decoded data that matches the data that was originally sent in a communications or data storage system. The iterative decoder includes a SISO channel detector and an ECC decoder and decodes the coded information according to at least one iterative decoding algorithm in regular decoding mode and/or at least one iterative decoding algorithm in error-recovery mode.
