    Abstract: The estimation and mitigation of swept-tone interferers includes receiving a composite signal comprising a signal of interest and a swept-tone interferer over an observation bandwidth. The estimation of the interfering signal may be based on modeling the interferer over the observation bandwidth as a magnitude periodic signal comprising non-overlapping, contiguous epochs, where each epoch may comprise a common pulse shape and a distinct phase rotation. The period of the magnitude-periodic signal may be initially determined, and the common pulse shape and each of the distinct phase rotations may then be estimated. These estimates may be used to reconstruct an estimate of the swept-tone interferer, which may be subtracted from the composite signal to generate an interference-mitigated signal of interest.

    Abstract: A method for interference estimation and mitigation includes receiving a high-resolution digital signal. The high-resolution digital signal comprises a signal of interest and an interfering signal. An estimate of the interfering signal is generated using a quantizer. The signal of interest is in a quantization noise of the quantizer. An interference-mitigated signal of interest is generated based on a difference of the estimate of the interfering signal and the high-resolution digital signal.
