    摘要: Code designs for channel coding with side information (CCSI) based on combined source-channel coding are disclosed. These code designs combine trellis-coded quantization (TCQ) with irregular repeat accumulate (IRA) codes. The EXIT chart technique is used for IRA channel code design (and especially for capacity-approaching IRA channel code design). We emphasize the role of strong source coding and endeavor to achieve as much granular gain as possible by using TCQ. These code designs synergistically combine TCQ with IRA codes. By bringing together TCQ and EXIT chart-based IRA code designs, we are able to approach the theoretical limit of dirty-paper coding.

    摘要: System and method for Slepian-Wolf coding using channel code partitioning. A generator matrix is partitioned to generate multiple sub-matrices corresponding respectively to multiple correlated data sources. The partitioning is in accordance with a rate allocation among the correlated data sources. Corresponding parity matrices may be generated respectively from the sub-matrices, where each parity matrix is useable to encode correlated data for a respective correlated data source, resulting in respective syndromes, e.g., in the form of binary vectors. A common receiver may receive the syndromes and expand them to a common length by inserting zeros appropriately. The expanded syndromes may be vector summed (e.g., modulo 2), and a single channel decoding applied to determine a closest codeword, portions of whose systematic part may be multiplied by respective submatrices of the generator matrix, which products may be added to the respective expanded syndromes to produce estimates of the source data.

    摘要: A system and method for realizing a Wyner-Ziv encoder may involve the following steps: (a) apply nested quantization to input data from an information source in order to generate intermediate data; and (b) encode the intermediate data using an asymmetric Slepian-Wolf encoder in order to generate compressed output data representing the input data. Similarly, a Wyner-Ziv decoder may be realized by: (1) applying an asymmetric Slepian-Wolf decoder to compressed input data using side information to generate intermediate values, and (b) jointly decoding the intermediate values using the side information to generate decompressed output data.
