ABSTRACT:
An interference canceller for cancelling an interfering signal generated by n interfering source from a transmission link between an antenna and a receiver. The interference canceller derives a sample of the interfering signal from the interfering source and down converts the sample to an intermediate frequency. A computer controlled delay path and computer controlled amplitude and phase modulator interatively adjusts a cancellation signal that is injected into the transmission link between the antenna and receiver to maximize the amplitude match between the cancellation signal and the interfering signal, and anti-phase the cancellation signal with respect to the interfering signal.
