Abstract

A method for error correction, the method comprises receiving a codeword that comprises a payload and a redundancy section; error-correction decoding the codeword by applying a syndrome-based error correction process to provide an amended payload and an error-correction decoding success indicator; wherein the amended payload comprises an amended CRC signature and an amended payload data; calculating, using the amended payload CRC signature, a validity of the amended payload to provide a CRC validity result; estimating a number of errors in the redundancy section; and determining that the error-correction succeeded when the number of errors in the redundancy section did not exceed a threshold, the error correction success indicator indicates that the error-correction decoding failed, and the CRC validity result indicates that the amended payload is valid.
