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 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.

1. A method, comprising:
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; scanning a known narrow band channel of the wide frequency band having a history of causing interference in the wide frequency band; and detecting according to one of the adaptive threshold, the average composite wideband power level, or both, interference in the wide frequency band caused by signals transmitted in the known narrow band channel.
