Claim:
1. An apparatus for interference cancellation in a wireless communication system with a diversity antenna configured for reception, comprising: a receive signal path configured to transfer an overall receive (Rx) signal comprising an Rx signal and a residual transmit (Tx) signal, from an antenna port to an Rx input port of a transceiver; at least one cancellation path configured to receive a leakage Tx signal from the antenna port; a cancellation unit configured to apply a cancellation signal, to the overall Rx signal in the receive signal path; a compensation unit configured to generate the cancellation signal by modifying the leakage Tx signal in the cancellation path, based on a compensation control signal; and a feedback receiver unit configured to generate the compensation control signal based on the residual Tx signal and the cancellation signal.
