Abstract:
1. A method of decoding data symbols, wherein the data symbols have been coded by using a linear block code, the method comprising: providing reliability information of the data symbols; selecting a first group of symbols from a first set of groups of symbols, wherein the first set of groups of symbols is defined by at least a first parity-check of a parity-check matrix of the linear block code, and wherein the selection is based on the reliability information; selecting a second group of symbols from a second set of groups of symbols, wherein the second set of groups of symbols is defined by at least a second parity-check of the parity-check matrix, wherein the at least second parity-check is different from the at least first parity-check, and wherein the selection is based on the selected first group of symbols and the reliability information; and composing at least a part of a codeword to comprise the first group of symbols and the second group of symbols.
