摘要： In a method of decoding data symbols into codewords, reliability information of the data symbols is provided. A first group of symbols from a first set of groups of symbols is selected, wherein the first set of groups of symbols is defined by at least a first parity-check of a parity-check matrix of a linear block code which has been used to encode the data symbols. The selection is based on the reliability information. A second group of symbols from a second set of groups of symbols is selected, wherein the second set of groups of symbols is defined by at least a second parity-check of the parity-check matrix. The selection is based on the selected first group of symbols and the reliability information. At least a part of the codeword is composed on the basis of the first group of symbols and the second group of symbols.

摘要： A method for retransmission of erroneous data in a communications system includes receiving data blocks at a receiver that have been generated in a transmitter by the use of an error correcting code. The received data blocks are decoded by a linear programming algorithm. One or more symbols in the decoded data block are identified by subjecting the symbols in the decoded data block to an integrality criterion. A retransmission of a part of the data block based on the one or more identified symbols is then initiated.
