Abstract:
A transceiver for reducing transmit signal leakage is described. The transceiver includes a downconverter that downconverts a receive signal to produce a feedback signal. The transceiver also includes a weight learning module that correlates the feedback signal with a transmit signal to obtain a weight. The transceiver further includes a transmit leakage estimator that obtains an estimated transmit leakage signal based on the weight and the transmit signal. The transceiver also includes a transmit leakage reducer that reduces the transmit leakage in the receive signal based on the estimated transmit leakage signal.
