Claim Text:
1. A method comprising: receiving a set of symbols of a reduced-alphabet codeword, the reduced-alphabet codeword representing a weighted sum of sub-channel code vectors wherein a weighting of each sub-channel code vector is based in part on a corresponding antipodal weight determined by a corresponding input bit in a set of input bits, and wherein the sub-channel code vectors form a reduced-alphabet weight matrix, and are mutually orthogonal to a common mode vector; and, forming a set of comparator outputs corresponding to the set of input bits, wherein each comparator output is formed using a respective multi-input comparator (MIC), wherein each respective MIC receives a subset of the symbols and has a set of input weights determined by a respective sub-channel code vector.
