A method and apparatus for noise cancellation in a multi-channel
communication system is disclosed. In one embodiment this system is
configured to cancel FEXT on a victim channel utilizing the signals
received on the other channels. The processing benefits gained by a
receiver's other filters, such as for example, the FFE and DFE filters,
is utilized when generating a FEXT cancellation signal. As a result, the
complexity of the apparatus that generates the FEXT cancellation signal
may be made less complex since part of the processing burden is performed
by other filter apparatus. In one configuration pre-code FEXT
cancellation occurs in that a pre-code FEXT filter generates one or more
pre-code FEXT cancellation signals corresponding to each of the other
channels. The pre-code FEXT cancellation signals are combined, prior to
transmission, with the signals associated with each of the other
channels, to thereby pre-cancel FEXT prior to transmission.
