Abstract:
1. A method, comprising: searching, by a communication device, for available spectrum in a particular radio frequency spectrum; selecting, by the communication device, a portion of available spectrum in the particular radio frequency spectrum independent of there being interference in the available spectrum; scanning, by the communication device, a wideband communication signal in the selected portion of spectrum at least once to determine a corresponding signal strength for each of a plurality of narrowband channels for each scan; determining, by the communication device, a corresponding correlation factor for each of the plurality of narrowband channels by correlating the corresponding signal strengths from the plurality of times each narrowband channel has been scanned; each scan, identifying, by the communication device, from the corresponding correlation factors for the plurality of narrowband channels, any of the plurality of narrowband channels that contain narrowband interference; and in response to an identification of at least one of the plurality of narrowband channels as containing narrowband interference, generating, by the communication device, tuning coefficient data to tune a filter frequency and a filter bandwidth of an adaptive digital filter apparatus for filtering the narrowband interference from the wideband communication signal.
