1. A method for reducing a dynamic range of a received radio frequency signal, the method comprising:
demodulating digital in-phase and quadrature signals of a received radio frequency signal to generate an instantaneous frequency signal;
determining an estimated center frequency of a selectable filter based at least in part on the instantaneous frequency signal;
selecting a center frequency of the selectable filter based at least in part on the estimated center frequency when an interfering signal is detected in a target frequency band of the received radio frequency signal; and
filtering the digital in-phase and quadrature signals using the selectable filter with the center frequency to generate output digital in-phase and quadrature signals.
