1. A method comprising:
- receiving, at a plurality of orthogonal subchannel multi-input comparators (MICs), a set of wire-specific inputs, each wire-specific input carrying a combination of a respective baseband symbol of a baseband codeword and at least one respective carrier-modulated symbol of at least one carrier-modulated codeword; and
generating a plurality of superposition subchannel signals, each superposition subchannel signal generated by a corresponding orthogonal subchannel MIC forming a respective subchannel-specific linear combination of the set of wire-specific inputs, each superposition subchannel signal comprising a respective superposition of (i) a baseband subchannel signal and (ii) one or more carrier-modulated subchannel signals, the baseband subchannel signal and the one or more carrier-modulated subchannel signals associated with the baseband codeword and the at least one respective carrier-modulated codeword, respectively.

Abstract
Transmission of baseband and carrier-modulated vector codewords, using a plurality of encoders, each encoder configured to receive information bits and to generate a set of baseband-encoded symbols representing a vector codeword; one or more modulation circuits, each modulation circuit configured to operate on a corresponding set of baseband-encoded symbols, and using a respective unique carrier frequency, to generate a set of carrier-modulated encoded symbols; and, a summation circuit configured to generate a set of wire-specific outputs, each wire-specific output representing a sum of respective symbols of the carrier-modulated encoded symbols and at least one set of baseband-encoded symbols.
