Pseudo product code decoding |
摘要 |
<p>A pseudo product code decoding apparatus has the following units: a first error correction code decoding unit for effecting error correction by using parity symbols of a first linear-structure error correction code contained in an input symbol train that constitutes a pseudo product code codeword; a second error correction code decoding unit for effecting error correction by using parity symbols of a second linear-structure error correction code; a second-series information symbol extracting unit for extracting second-series information symbols; a subtraction code generating unit for generating a subtraction code of a pseudo product code codeword formed of the second-series information symbols, with the first-series information symbol portion and the second linear-structure error correction code portion being changed to zero codes; a transforming unit for transforming the pseudo product code codeword into a product code codeword through execution of subtracting processing with the subtraction code; an error correction code repetitive decoding unit for effecting decoding processings a plurality of times, thereby effecting error correction; and a first-series information symbol extracting unit for extracting the first-series information symbols. <IMAGE></p> |
