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 scanning wireless signals in a wide frequency band, measuring power levels in narrow frequency bands from the wireless signals, determining a threshold according to an average wideband power level or at least a portion of the power levels in the narrow frequency bands, detecting from the wireless signals a narrow band interferer based on the threshold, and initiating a strategy for responding to interference in the wide frequency band caused by the detected narrow band interferer. Other embodiments are disclosed.

主权项

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 adaptive threshold based on at least some of the narrow band signal power levels; detecting a narrow band interferer according to the adaptive threshold; responsive to a detection of the narrow band interferer, obtaining identification information for a source of the narrow band interferer; and initiating a strategy for responding to interference in the wide frequency band caused by the detected narrow band interferer, wherein the initiating of the strategy is according to the identification information.
