Abstract
In a method of transmitting data between a transmitter and a receiver via two pairs of wires in a differential mode, the method comprises transmitting, from the transmitter to the receiver, related signals onto the two pairs of wires in respect of each tone in a first subset of tones and processing the received signals in dependence upon estimated channel transfer functions associated with both direct and crosstalk channels. The method further comprises transmitting, from the transmitter to the receiver, unrelated signals onto the two pairs of wires for each tone in a second subset of the tones, the unrelated signals being vector precoded before transmission and wherein a cut-off frequency and/or tone demarcates between the first and the second subsets of tones.
