In the proposed scheme, syndromes of row-vector and column-vector are calculated from the hard-decision sequence of a received sequence, and error patterns are calculated by the table-aided decoding. The error patterns are used to change the soft-input for the decoder into more reliable values. The changed soft-input is used as the soft-input for the next decoder. Iterating this process, the proposed scheme improves the performance of bit error rate remarkably. The proposed scheme also reduces the computational complexity by using the
