Method and device for maintaining the performance quality of a communication system in the presence of narrow band interference

摘要

A system that incorporates teachings of the subject disclosure may include, for example, a method for analyzing a wide frequency band with respect to signal power levels in specified narrow frequency bands, detecting narrow band signal power levels received in the specified narrow frequency bands, determining an average composite wideband power level from the narrow band signal power levels, determining an adaptive threshold, detecting narrow band interference according to one of the average composite wideband power level, the adaptive threshold, or both, prioritizing the detected narrow band interference, and selectively filtering a portion of the detected narrow band interference according to the prioritization. Other embodiments are disclosed.

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.
