Abstract:
1. A transmit system configured as part of a first station, the first station having two or more transmitters, each associated with a channel, configured as part of a multi-channel communication system configured to modify a data signal prior to transmission by the transmitter from the first station to a second station to reduce the effects of coupling on the data signal, at least one of the transmitters in the transmit system 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, prior to transmission of the data signal, FEXT coupling from the first channel to one or more other channels; and a device configured to combine one or more incoming cancellation signals from the one or more other transmitters within the transmit system with the signal, the one or more incoming cancellation signals arriving from the one or more other transmitters in the multi-channel communication system to cancel, prior to transmission of the data signal, FEXT coupling from the one or more other channels to the first channel.
