1. A method, comprising:

  • scanning, by a processor, a wide frequency band with respect to signal power levels in specified narrow frequency bands;

    measuring, by the processor, narrow band signal power levels received in the specified narrow frequency bands;

    determining, by the processor, an average wideband power level by excluding a portion of the narrow band signal power levels measured;

    determining, by the processor, an adaptive threshold according to the average wideband power level;

    detecting, by the processor, narrow band interferers according to the adaptive threshold; and

    identifying, by the processor, a prioritization of the narrow band interferers.
