FIELD: information technology.
SUBSTANCE: result is achieved by receiving a received (RX) input RF-signal, having a TX-leakage signal; subtracting the estimate of the TX-leakage signal from the input signal and generating an estimate of the TX-leakage signal which does not include the TX-signal itself, based on the output signal and an unmodulated reference signal at the carrier frequency of the TX-leakage signal.
EFFECT: reduced negative effect of second-order distortion and distortion from cross-modulation of signal leakage from the transmitting device.
