Abstract

This paper proposes a simple iterative decoding algorithm of product codes by using table-aided soft-decision decoding, in which the table of error patterns corresponding to their syndromes is used to limit the number of the candidate codewords. 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 table-aided
