Abstract: Various schemes for mitigating radio frequency (RF) interference are described, wherein an adaptive local oscillator (LO) is utilized. A receiver measures a jamming indicator which indicates a total power within a receiving band of the receiver. If the jamming indicator indicates a presence of substantial in-band interference, the receiver may program the LO to a different frequency and/or adjust a bandwidth of a filter accordingly to reject or reduce the interference. The receiver may adjust the LO and/or the filter repeatedly until the interference is rejected to a point that de-sense to the signal intended to be received is satisfactorily mitigated. The receiver may restore the LO and the filter to a default setting when the jamming indicator indicates that the interference is no longer present.
