1. A device comprising:
- a memory to store instructions; and
a circuit coupled to the memory, wherein execution of the instructions by the circuit causes the circuit to perform operations comprising;
detecting narrow band signal power levels received in a group of channels of a wide frequency band, wherein the detecting of the narrow band signal power levels is according to an analysis order for a group of channels, wherein the analysis order is non-sequential and is determined based on a probability of having interference;
determining an average wideband power level from less than all of the narrow band signal power levels;
detecting interference associated with a channel based on the average wideband power level, to obtain a detected interference; and
initiating an interference mitigation strategy according to the detecting of the interference.

Abstract
A system that incorporates teachings of the subject disclosure may include, for example, a method for measuring power levels in narrow frequency bands of signals provided by a radio frequency receiver configured to scan radio frequency signals over a wide frequency band, calculating an average wideband power level from at least a portion of the measured power levels, determining a threshold from the average wideband power level, the portion of the measured power levels in the narrow frequency bands, or both, detecting from the signals narrow band interference based on the threshold, and substantially suppressing the detected narrow band interference. Other embodiments are disclosed.
