1. A method comprising:
- obtaining a set of information bits;
generating a set of spectral-shaped pre-coded signals from the set of information bits based on a previous set of information bits and a superposition of a plurality of mutually orthogonal sub-channel code vectors, each sub-channel code vector associated with a respective information bit of the set of information bits and a corresponding information bit of the previous set of information bits; and
transmitting the set of spectral-shaped pre-coded signals over respective wires of a multi-wire bus.

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.
