Abstract:
An apparatus for interference cancellation in wireless communication systems configured for reception, comprises a receive signal path configured to convey 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, and at least one cancellation path configured to receive a leakage Tx signal from the antenna port. Further, the apparatus comprises a cancellation unit configured to apply a cancellation signal to the overall Rx signal in the receive signal path and 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. In addition, the apparatus comprises a feedback receiver unit configured to generate the compensation control signal based on the residual Tx signal in the overall Rx signal and the cancellation signal.
