1. A controller for a radio frequency (RF) receiver operable in a wireless signaling environment having a plurality of radio frequency (RF) signals originating from multiple sources utilizing multiple frequency bands, wherein the controller is configured to:
determine an RF background signature based at least in part on one or more characteristics of the plurality of RF signals received via at least one antenna during a first period of time from the multiple sources;
extrapolate at least part of the RF background signature in at least one frequency band of interest of the multiple frequency bands for use in a second period of time occurring, at least in part, after the first period of time; and
identify, during the second period of time, a signature of a first RF signal of the plurality of RF signals received via the at least one antenna from a first source of the multiple sources utilizing the at least one frequency band of interest in the presence of at least a second RF signal of the plurality of RF signals.
