Abstract:
1. An electromagnetic radiation receiving method, comprising: modeling at least one signal within an electromagnetic radiation band; generating at least one digital reference signal corresponding to the modeled at least one signal; converting the at least one digital reference signal to at least one corresponding analog reference signal, wherein at least a delay and a magnitude of the at least one corresponding analog reference signal are controllable; combining a received waveform within the electromagnetic radiation band containing the at least one signal and an information carrier 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 of the at least one corresponding analog reference signal 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 information carrier is substantially undistorted; generating at least one cancellation signal, corresponding to a residue of the at least one signal in the residue signal, controllable with respect to at least waveform, 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 waveform, magnitude, and delay and, 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 the information carrier is substantially undistorted.
