Abstract

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 from the average composite wideband power level, detecting narrow band interference according to the adaptive threshold, and configuring a filter to substantially suppress the detected narrow band interference. Other embodiments are disclosed.
