  • Patent number: 9112532
    Abstract: A QC-LDPC decoding system employing a trapping set look-up table is provided. The QC-LDPC decoding system includes an iterative decoder that utilizes a message-passing algorithm to decode a received codeword. If the iterative decoder fails to produce a valid codeword, additional processing is performed to decode the received codeword. The additional processing includes the steps of computing the syndrome pattern of the received codeword, searching the look-up table for a trapping set class that is responsible for the iterative decoder's failure, retrieving from the look-up table a syndrome pattern and an error pattern of a member of the responsible trapping set class, and calculating the error pattern of the received codeword based on its syndrome pattern and the information retrieved from the look-up table. The received codeword is then corrected based on its error pattern.

  • Patent number: 9048879
    Abstract: An error correction system includes an iterative code that employs an interleaved component code and an embedded parity component code. In some embodiments, 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. At least a portion of the first set of codewords preferably is divided into a plurality of symbols which are encoded based on the embedded parity code to provide encoded data. Similarly, in some embodiments, 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 preferably is used, together with other soft information, by an interleaved decoder to generate reliability metrics for biasing a subsequent decoding iteration.
