  • Comb limiter combiner with sub-band interference negation
    Patent number: 9628217
    Abstract: Aspects of the present invention provide a system and method for using a filter controller and an adjustable narrow-band filter within each sub-band of a communication system. If a channel of the sub-band is being jammed, the filter controller will adjust the adjustable narrow-band filter to notch-filter out only the channel of the sub-band that is being jammed. In this manner, the remaining channel of the sub-band may be used for communication.
