Abstract:
A decoding apparatus for decoding an error correction code interleaved on a transmitting side and deinterleaved on a receiving side, comprising:a determining circuit for checking each word of the error correction code to make determination as to whether decoding is acceptable or not according to a result of decoding;an error position detector for obtaining error position data by detecting an error position in decoding bit by bit according to the result of decoding;an estimator for estimating an error position according to error position data detected by said error position detector in a word adjoining a correction object word when said determining circuit determines that decoding is not acceptable;a correcting circuit for correcting said correction object word according to the error position estimated by said estimator; anda redecoder for executing redecoding processing according to a result of correction by said correcting circuit.
