    摘要: In one embodiment, a system includes a controller and logic integrated with and/or executable by the controller. The logic is configured to perform iterative decoding on encoded data to obtain decoded data. At least three decoding operations are performed in the iterative decoding, with the decoding operations being selected from a group consisting of: C1 decoding and C2 decoding. The logic is also configured to perform post-decoding error diagnostics on a first portion of the decoded data in response to not obtaining a valid product codeword in the first portion after the iterative decoding of the encoded data. Other systems, methods, and computer program products for producing post-decoding error signatures are presented in accordance with more embodiments.

    摘要: A digital television (DTV) transmitting system includes a first frame decoder, a second frame decoder, and a frame multiplexer. The first frame decoder forms first enhanced data frames, encodes each data frame for error correction, forms a first super frame by combining the encoded first frames, and interleaves the first super frame. The second frame decoder forms second enhanced data frames, encodes each data frame for error correction, forms a second super frame by combining the encoded second frames, and interleaves the second super frame. The frame multiplexer multiplexes the interleaved first and second enhanced data frames.

    摘要: Methods and devices are provided for coding and decoding coded data including source data and redundancy data. The redundancy data is obtained by applying, upon coding, an error correction code to the source data, implementing a generating matrix. The generating matrix includes, in its systematic form, an identity matrix and an invertible matrix for switching from the source data to the redundancy data. The coding or decoding is based on a Tanner graph, which combines the graph of the error corrector code and the graph of the dual code of the error correction code by superimposing these graphs.
