1. A method, comprising:
scanning, by a communication device, a radio frequency spectrum; identifying, by the communication device, an available frequency band in the radio frequency spectrum; determining, by the communication device, a signal strength for each of a plurality of narrowband channels in the available frequency band; determining, by the communication device, a correlation factor for at least a portion of the plurality of narrowband channels by correlating the signal strength for each of the plurality of narrowband channels; identifying, by the communication device, from the correlation factor a narrowband channel of the plurality of narrowband channels having narrowband interference; repeating, by the communication device, a determination of the correlation factor and an identification of the narrowband channel until a desired confidence level that the narrowband channel is being affected by interference has been achieved, wherein a determination that the desired confidence level has been achieved is according to a comparison of the correlation factor with a correlation factor threshold; generating, by the communication device, tuning coefficient data to substantially suppress the narrowband interference in the narrowband channel responsive to achieving the desired confidence level; and configuring filters according to the tuning coefficient data to substantially suppress the narrowband interference in the narrowband channel, wherein the configuring of the filters comprises tuning the filters to filter frequencies and filter bandwidths according to the tuning coefficient data that includes a frequency and a bandwidth coefficient pair for each of the filters, that instructs a corresponding filter as to a frequency to be tuned for bandpass or bandstop operation and a bandwidth to be applied for the bandpass or bandstop operation. |
