Claim Text:
1. A method, comprising: identifying, by a system including a processor, an available frequency band in a radio frequency spectrum, wherein a portion of the available frequency band is subject to undesirable radio frequency interference; selecting, by the system, the available frequency band for engaging in communications independent of there being interference in the available frequency band; determining, by the system, a signal strength for each of a plurality of narrowband channels in the available frequency band; determining, by the system, 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 system, from the correlation factor a narrowband channel of the plurality of narrowband channels that contains narrowband interference; and generating, by the system, first tuning coefficient data for configuring a filter for filtering the narrowband interference in the narrowband channel for communicating in the narrowband channel, wherein the generating of the tuning coefficient data is according to first information received from a first signal sampler, wherein the first information is associated with input signals to the filter; and generating, by the system, second tuning coefficient data for configuring the filter to be adjusted for filtering the narrowband interference in the narrowband channel, wherein the generating of the second tuning coefficient data is according to second information received from a second signal sampler, wherein the second information is associated with output signals from the filter, wherein the tuning coefficient data enables the filter to pass first radio signals associated with a first wireless protocol and to filter second radio signals associated with a second wireless protocol, and wherein the filtering of the narrowband interference based on the first tuning coefficient is independent of the first wireless protocol.
