Patent ID: 8681844

Claim:
A method, comprising: scanning, by a device, a radio frequency spectrum; identifying, by the device, an available frequency band in the radio frequency spectrum; selecting, by the device, the available frequency band for engaging in communications independent of there being interference in the available frequency band; determining, by the device, a signal strength for each of a plurality of narrowband channels in the available frequency band; determining, by the 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 device, from the correlation factor a narrowband channel of the plurality of narrowband channels that contains narrowband interference; generating, by the device, tuning coefficient data to substantially suppress the narrowband interference in the narrowband channel; configuring, by the device, a filter according to the tuning coefficient data to substantially suppress the narrowband interference in the narrowband channel and produce a digital filtered signal; and transmitting, by the device, the digital filtered signal to a base station.
