摘要: This disclosure describes techniques for reducing adverse effects of transmit signal leakage in a full-duplex, wireless communication system. The second order distortion and cross-modulation from transmitter via duplexer. may be effective rejecting at least portion signal, thereby or eliminating distortion. adaptive filter include an estimator circuit that generates estimate. A summer subtracts the estimate received to cancel produce output signal. based on reference feedback approximates carrier used generate transmitter. provided by same oscillator
