1. A method, comprising:
- measuring, by a system comprising a processor, within a wide frequency band, signal power levels received in specified frequency bands;
determining, by the system, an average composite wideband power level that excludes a portion of the signal power levels;
determining, by the system, an adaptive threshold from the average composite wideband power level;
detecting, by the system, interference according to the adaptive threshold; and
configuring, by the system, an adjustable bandwidth of a filter to suppress at least a portion of the interference.
