Abstract (en)

[origin: WO8907864A1] The effects of multipath and other interference signals in communication receivers are reduced by using adaptive signal processing. The feedback of the adaptive signal processor (104) is changed so that an external reference signal is not required. The invention addresses a signal environment in which the directions of arrival and the times of arrival of the signal of interest and the unwanted multipath or interference signals are unknown. The system uses the strongest received signal as the signal of interest.
