摘要： Embodiments of the present invention provide a forward error correction codeword synchronization method, device, and system. The method is: sending, by a central office device, synchronization information of an FEC codeword to a terminal device by using a management channel, where the information includes information about an agreed location of an FEC codeword, and the information about the agreed location of the first FEC codeword indicates a location that is of the first FEC codeword and is corresponding to data at an agreed location of an agreed time-frequency resource block; and receiving, by the terminal device, the synchronization information that is of the FEC codeword and is sent by the central office device, and adjusting a status parameter of an encoder or a decoder according to the information, so as to complete codeword synchronization. The embodiments of the present invention are used for FEC codeword synchronization.

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. 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： 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.

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： A method and apparatus are disclosed for MAP decoding of signals encoded using error correction codes to make maximum probability decisions about each transmitted bit. A disclosed MAP decoding algorithm extends the work of Hartman and Rudolph and exploits properties of Hamming error correction codes to provide a decoding algorithm having a complexity that is proportional to n log n for Hamming codes. The invention computes a difference, ρ, of the probabilities the that transmitted symbol was zero and one based on characteristics of the channel and then determines the product of the ρl values corresponding to non-zero positions of codewords of the dual code using real vector and 2[2]-vector fast Walsh-Hadamard transforms. The invention also processes all positions of all codewords to determine a sum for each position that indicates the reliability that a received bit is a given value for a given position using the real vector fast Walsh-Hadamard transforms.
