发明名称 Multi-source data encoding, transmission and decoding using Slepian-Wolf codes based on channel code partitioning
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.
