Systems and methods are provided for correcting absorb sets and near absorb sets in the (2048, 1723) LDPC code used in 10GBase-T transmission systems. Absorb sets and near absorb sets correspond to error patterns that, due to the structure and imperfections of the LDPC code, cannot easily be corrected using standard correction methods. To correct these error patterns, a set of failed syndrome checks associated with the error pattern can be identified, and the 4, 8, 12, or 16 error patterns associated with the failed syndrome checks can be determined. The codeword may then be corrected based on the error pattern that most likely occurred. |
