Synchronously-switched multi-input demodulating comparator

A method comprising:

• receiving wire signals comprising a superposition of a set of baseband symbols and a set of carrier-modulated symbols;
• generating, using a set of baseband multi-input comparators (MICs) a set of baseband sub-channel outputs by combining the set of wire signals according to the respective input permutations associated with respective sub-channel vectors of a plurality of mutually orthogonal sub-channel vectors;
• obtaining a phase-adjusted demodulation signal associated with the set of carrier-modulated symbols;
• and
• generating, using a set of combined MIC-demodulation circuits, a set of demodulated sub-channel outputs by combining the set of wire signals according to the respective input permutations, and according to the phase-adjusted demodulation signal operating to control a polarity of the respective input permutation to match a polarity of the set of carrier-modulated symbols.
