摘要
An apparatus for interference cancellation in a wireless communication system, includes a cancellation unit configured to receive a transmit (Tx) signal from an output port of a power amplifier and a receive (Rx) signal from an antenna, and generate a cancellation of a primary portion of the Tx signal from the Rx signal at an output thereof, leaving a residual portion as a residual Tx signal, wherein the output of the cancellation unit is coupled to an Rx input port of a transceiver. The apparatus further includes a compensation control unit configured to modify one or more signals within the cancellation unit, based on the residual Tx signal at the output of the cancellation unit.
