Abstract: System and method for designing Slepian-Wolf codes by channel code partitioning. A generator matrix is partitioned to generate a plurality of sub-matrices corresponding respectively to a plurality of correlated data sources. The partitioning is performed in accordance with a rate allocation among the plurality of correlated data sources. A corresponding plurality of parity matrices are generated based respectively on the sub-matrices, where each parity matrix is useable to encode data from a respective one of the correlated data sources.

Abstract: 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.

Abstract: Apparatus, and an associated method, for designing codes to be used to code data that is communicated in a multi-access communication system. A selected code is designed, based upon an initial code. The selected code that is designed is of characteristics that best optimize channel differentiation to minimize interference between concurrently-communicated data coded by different codewords of the selected code.

Abstract: Doppler correction system and method comprising receiving a Doppler effected signal comprising a preamble signal (32). A delayed preamble signal (48) may be generated based on the preamble signal (32). The preamble signal (32) may be multiplied by the delayed preamble signal (48) to generate an in-phase preamble signal (60). The in-phase preamble signal (60) may be filtered to generate a substantially constant in-phase preamble signal (62). A plurality of samples of the substantially constant in-phase preamble signal (62) may be accumulated. A phase-shifted signal (76) may also be generated based on the preamble signal (32). The phase-shifted signal (76) may be multiplied by the delayed preamble signal (48) to generate an out-of-phase preamble signal (80). The out-of-phase preamble signal (80) may be filtered to generate a substantially constant out-of-phase preamble signal (82). A plurality of samples of the substantially constant out-of-phase signal (82) may be accumulated.
