In order to realize a high-coding-gain forward error correction scheme for fading environments, a novel concatenated coding scheme employing soft decision decoding with channel-status-information (CSI) for inner codes and also soft decision decoding for outer codes (Double side information concatenated coding scheme) is proposed and its performance is clarified by a hardware experiment employing the developed ultra-high-speed (operation speed up to 60MHz) and universal-coding-rate (from coding rates one-half to fifteen-sixteenths) Viterbi decoder VLSIC (SNUFEC VLSI). The proposed scheme improves the Pe performance to 1/3 of conventional one by employing the SNUFEC VLSI which can output the path memory circuit status 1,0 ratio as the soft-decision decoding data for likelihood information.
