  • Amplitude domain circuits and methods for reducing an interference signal that spectrally overlaps a desired signal
    Patent number: 10340962
    Abstract: Under one aspect, a method for reducing interference in a received signal can include splitting a received signal into a first portion and a second portion, the received signal comprising a desired signal and an interference signal that spectrally overlaps the desired signal. The method also can include estimating an amplitude A(t) of the first portion as a function of time. The method also can include suppressing at least a portion of the interference signal in the estimated amplitude A(t) to generate an interference suppressed amplitude A?(t). The method also can include delaying the second portion by an amount of time corresponding to the estimation and suppression. The method also can include multiplying the interference suppressed amplitude A?(t) by the delayed second portion to obtain an output having reduced contribution from the interference signal.
