| 1. A transceiver, comprising:
a) a receiver portion including at least one receiver to receive signals from a complementary transmitter through a transmission
medium, the at least one receiver including a plurality of demodulators to receive the signals from a corresponding plurality
of frequency separated channels: and
b) an interference filter coupled to the receiver portion to substantially reduce interference in signals received by the
receiver portion that result from transmission coupled to each of the plurality of corresponding frequency separated channels
from transmitters other than the complementary transmitter
wherein the interference filter includes a far-end cross-talk filter and the far-end cross-talk filter receives input signals
from each of the plurality of demodulators of each of the at least one receiver and removes interference from each of the
signals in the receiver portion by subtracting a selected portion of each of the input signals from each of the signals in
the receiver portion.
