Methods and systems are described for receiving a set of input bits at a plurality of drivers and responsively generating an ensemble of signals, each respective signal of the ensemble of signals generated by receiving a subset of input bits at a respective driver connected to a respective wire of a multi-wire bus, the received subset of bits corresponding to sub-channels associated with the respective wire, generating a plurality of weighted analog signal components, each weighted analog signal component (i) having a corresponding weight and sign selected from a set of wire-specific sub-channel weights associated with the respective wire and (ii) modulated by a corresponding bit of the received subset of bits, and generating the respective signal by forming a summation of the plurality of weighted analog signal components at a common node connected to the respective wire for transmission over the respective wire of the multi-wire bus.
