Abstract
A system includes a first duplexer that receives samples of a signal transmitted from a first transmit portion of a communication device and outputs a filtered signal based on sampled transmitted signal. A first modulator adjusts the filtered signal based on at least one of a phase, amplitude, and delay of leakage associated with the transmitted signal. The leakage corresponds to leakage from the first transmit portion of the communication device to a first receive portion of the communication device. The first modulator provides a leakage cancellation signal based on the adjusted filtered signal. A first coupler subtracts the leakage cancellation signal from a signal received by the first receive portion of the communication device.
