Patent ID: 7567666

Claim:
A transmitter configured to modify a data signal prior to transmission on a channel by the transmitter to reduce the effects of coupling on the data signal, the transmitter comprising: an input configured to receive a data signal, the data signal to be transmitted over a first channel after processing by the transmitter; one or more filters configured to generate one or more outgoing cancellation signals, the one or more outgoing cancellation signals to be provided to one or more other transmitters in the transmit system to cancel FEXT coupling from the first channel to one or more other channels prior to transmission of one or more other data signals from the one or more other transmitters; and a device configured to combine one or more incoming cancellation signals from the one or more other transmitters with the signal, the one or more incoming cancellation signals arriving from the one or more other transmitters to cancel, prior to transmission of the data signal, FEXT coupling from the one or more other channels to the first channel.
