Abstract
At least a method and an apparatus are presented for determining a coded modulation scheme, the coded modulation scheme being defined by at least one non-binary error correcting code containing at least one non-binary parity-check equation, a modulation scheme, and a modulation mapping. Two or more candidate modulation mappings and two or more candidate parity-check equations are determined defining the at least one non-binary error correcting code, a candidate set comprising a candidate modulation mapping and at least one candidate parity-check equation providing codeword vectors and being associated with one or more metrics, each metric being evaluated for a number of distinct pairs of codeword vectors having an Euclidean distance of a defined value. One candidate modulation mapping and at least one candidate parity-check equation are selected according to an optimization criterion applied to the one or more metrics.
