Patent ID: 7092352

Claim:
An electromagnetic receiver system adapted to receive and separate at least one desired information signal from at least one interfering signal, the receiver system including: a plurality of electromagnetic receivers adapted to be responsive to electromagnetic signals including the at least one transmitted desired electromagnetic signal and the at least one transmitted interfering electromagnetic signal, the receivers being spatially separated to receive different proportions of the at least one transmitted desired electromagnetic signal and the at least one transmitted interfering electromagnetic signal, the receivers generating a plurality of received signals, a plurality of time-to-frequency converters wherein at least one of the converters is coupled to each of the receivers, each of the converters adapted to decompose the received signals into a plurality of frequency components, at least one of the frequency components produced by at least one of the converters including at least one desired signal frequency component and at least one interfering signal frequency component, and a frequency-dependent canceller coupled to the converters adapted to process the filtered received signals corresponding to the at least one frequency, the canceller adapted to provide at least one complex-valued weight to at least one frequency component generated by at least one of the converters to compensate for the different proportions of the at least one transmitted desired electromagnetic signal and the at least one transmitted interfering electromagnetic signal resulting from at least one of: a) differences in propagation of the electromagnetic signals to the plurality of electromagnetic receivers, and b) differences in the responsiveness of the electromagnetic receivers to the electromagnetic signals, the canceller adapted to combine the receive signals to separate at least one of the desired signal components by canceling at least one of the interfering signal components.
