Abstract

Systems and methods are provided for processing a time-domain signal in rectangular coordinates. The signal can include a low power desired signal and a high power, approximately constant envelope interference signal that spectrally overlaps the desired signal. A rectangular to polar converter can obtain magnitude and phase of the time-domain signal in polar coordinates. An interference estimator can estimate a magnitude of the interference signal based on the magnitude of the time-domain signal in polar coordinates. A subtractor can obtain a difference magnitude in polar coordinates based on the magnitude of the time-domain signal and the estimated magnitude of the interference signal in polar coordinates. A polar to rectangular converter can obtain the desired signal with reduced power of the interference signal based on the difference magnitude and phase of the time-domain signal in polar coordinates.
