Patent ID: 8102950

Claim:
A method for decoding a group of symbols from a set of received signal samples that depend on each symbol of the group to an extent depending on an associated dependence coefficient, comprising: computing first modified signal samples using said received signal samples; for each possible combination of all except at least one symbol in said group of symbols, subtracting from said first modified signal samples a dependence on said combination of symbols, as described by said associated dependence coefficients; determining a value for the remaining at least one symbol that is the nearest symbol value in the symbol alphabet, to obtain a quantized value for said at least one remaining symbol; and associating the quantized symbol value with the combination of other symbols to obtain a candidate symbol group; and for each candidate symbol group, computing a metric that indicates how well the candidate symbol group corresponds to said set of received signal samples; and selecting the candidate symbol group having a best one of said metrics.
