ABSTRACT:
In a case where error correction code interleaved in the transmitting side and deinterleaved in the receiving side is subjected to decoding processing, a control circuit determines whether a result of decoding for each word is acceptable or not according to decoding acceptable/unacceptable data for each word stored in a decoding acceptable/unacceptable data memory, and subjects a correction object word not decoded to redecoding processing by controlling an error position estimating circuit and correcting data for the correction object word with an estimated error locator based on error position data for a forward word as well as a backward word from the correction object word.
