Abstract
Recently, the encoding/decoding systems based on concatenated codes with several error correction codes are actively studied and effective performance improvements are obtained. In this report, the system for recoding code is proposed using a high dimensional parity check code known as a concatenated code with high error correction capability in digital communication. Especially, our soft decision decoding method is based on error detection using a parity check (tentative decision) and threshold decision for the reliability of error symbols (final decision). As a result, it is clear that the performances of these parity check codes are superior to that of the conventional 16/17(0,6/6) code.
