PROBLEM TO BE SOLVED: To provide a means for realizing high-speed maximum likelihood decoding processing. SOLUTION: An input signal is divided into blocks by a signal distributor (103), and successively supplied to one of a plurality of maximum likelihood decoders (104). In each decoder, the input signal is stored in a buffer storage device (106), decoding processing is performed at a low speed, and results are outputted in parallel from the buffer storage devices (108). A maximum likelihood decoder of the required operating speed is provided by low-speed circuit technology. Further, centralized control of serial/parallel conversion is made within the decoder, thereby supplying results of processing in parallel at a low speed to signal processing apparatuses, after decoding processing.
