Abstract:
A method for processing a radio frequency signal, the method comprising the steps of:receiving a composite signal including a signal of interest and an interfering signal; processing the composite signal to produce an output signal; controlling the magnitude of the output signal and the magnitude of the composite signal in response to the power of a signal component removed during the processing step; and combining the output signal and the composite signal to produce a blended signal; wherein the step of processing the composite signal to produce an output signal comprises the steps of: normalizing the composite signal to produce a normalized composite signal; multiplying the composite signal by a complex conjugate of the normalized composite signal to produce a real signal; filtering the real signal to produce a filtered signal; and multiplying the filtered signal by the normalized composite signal to produce the output signal.
