Patent number: 7885355Abstract: The present invention is a system and a method of filtering a signal at a receiver, the signal having at least a desired channel and blockers. A first converter converts a first copy of the signal resulting in a relatively narrow band, high-resolution first signal. A second converter converts a second copy of the signal resulting in a relatively wide band, low-resolution second signal. Once each copy of the signal is converted, the copies are passed to a combiner. At the combiner, the two copies of the signal are analyzed and the desired channel is extracted from the first copy of the signal by removing any inter-modulation product caused by any interference detected in the second copy from the blockers (not detected in the first copy).Type: GrantFiled: October 15, 2007Date of Patent: February 8, 2011Assignee: Cobham Defense Electronic CorpInventors: Laurent Claude Perraud, Robert Gyorgy Egri
