Patent ID: 8902724

Claim:
A method of cross-talk cancellation in a transceiver having a transmitter which signal processes and transmits a transmit signal, and a receiver which receives and signal processes a receive signal, the receive signal including therein a transmit cross-talk signal being at least a partial representation of the transmit signal, the method comprising: obtaining the transmit signal to be signal processed and transmit by the transmitter; signal processing the transmit signal to produce a cross-talk cancellation signal, the signal processing comprising applying to the transmit signal one or more signal processing operations which emulate the generation of the transmit cross-talk signal from the transmit signal in the receiver, and amplifying the transmit signal by one or more gains applied to the receive signal by one or more corresponding amplifiers in the receiver; and combining, in the receiver, the cross-talk cancellation signal with the receive signal containing the transmit cross-talk signal to thereby substantially remove or reduce the transmit cross-talk signal from the receive signal.
