Error correction system using an iterative product code

摘要

An error correction system includes an iterative code that employs an interleaved component code and an embedded parity component code. On the transmission side, input signals received at an input node are encoded based on the interleaved code, which encodes an interleaved version of the input data to produce a first set of codewords. A portion of the first set of codewords is divided into a plurality of symbols which are encoded based on the embedded parity code. On the receiving side, received data are detected to produce detected information and soft outputs. The detected information is decoded based on the embedded parity code to obtain decoded information. The decoded information is used with other soft information by an interleaved decoder to generate reliability metrics for biasing a subsequent decoding iteration.
