Abstract: A transceiver for reducing a distortion component within a baseband receive signal is provided. The distortion component is caused by a baseband transmit signal. The transceiver includes a filter configured to filter the baseband transmit signal using a configurable transfer function to generate a modified baseband transmit signal. The configurable transfer function is based on a leakage component in the baseband receive signal, wherein the leakage component is caused by the baseband transmit signal. The transceiver further includes a processing unit configured to generate, based on the modified baseband transmit signal, an envelope signal representing the envelope of the modified baseband transmit signal. Moreover, the transceiver includes a combiner configured to combine the baseband receive signal and a signal related to the envelope signal.
