Abstract
Pre-scaled orthogonal differential vector signalling (ODVS) techniques are described. The ODVS encoding schemes described herein generate one sub-channel for each bit by multiplying each bit by a different row in a transmitter encoding matrix to produce a set of sub-channels. Each wire carries a signal that is a superposition of elements from all of the sub-channels in the set. The transmitter encoding matrix is selected such that its rows (i.e. sub-channels) are mutual orthogonal. This means that the receiver can decode the signals received from all wires in concert to reliably recover the original bits. The transmitter encoding matrix is a Hadamard matrix in some cases. This disclosure is particularly focussed on ODVS techniques that apply a scaling factor, termed a 'pre-scaler', to a weaker sub-channel or sub-channels within the set of sub-channels so as to boost that/those sub-channel(s) relative to the other sub-channels.
