Patent Document ID: 6012158
Application ID: 08770643

Base Claim:
1. 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; and a redecoder for executing redecoding processing according to a result of correction by said correcting circuit.

Claim 2:
2. A decoding apparatus according to claim 1; wherein said error correction code is a BCH error correction code.
