摘要
A communication channel is disclosed comprising a trellis sequence detector for detecting an estimated data sequence from signal sample values. A post processor detects and corrects an error event of the trellis sequence detector by remodulating the estimated data sequence into a sequence of expected sample values, computing samples errors as the difference between the expected samples and signal samples, and correlating the sample errors with error event samples. The communication channel further comprises a Reed-Solomon error correction code (ECC) decoder for decoding a Reed-Solomon codeword in the estimated data sequence in response to the detected error event.
