Claim One:
1. An electromagnetic radiation receiving method, comprising: generating at least one analog reference signal corresponding to a frequency and phase of at least one signal within an electromagnetic radiation band, the at least one analog reference signal being generated in dependence on a digital model of the at least one signal which is controlled for at least amplitude and delay; combining a received waveform within the electromagnetic radiation band containing the at least one signal and a further signal modulated with information with the at least one corresponding analog reference signal in a first analog combiner to generate a first residue signal, at least the delay and magnitude being controlled such that a magnitude of the at least one signal within the first residue signal is reduced with respect to the received waveform and the further signal modulated with information is substantially undistorted; generating at least one cancellation signal, selectively dependent on a residue of the at least one signal in the residue signal, controllable with respect to at least magnitude and delay based on a feedback input; combining the first residue signal with the at least one cancellation signal in a second combiner to generate a second residue signal; and generating the feedback input based on at least the second residue signal to control said generating the at least one cancellation signal with respect to at least magnitude, and delay, such that a magnitude of the at least one signal within the second residue signal is reduced with respect to the first residue signal; and demodulating the information.
