Abstract:
1. A method comprising: analyzing, by a system comprising a processor, a wide frequency band with respect to signal power levels in specified narrow frequency bands; detecting, by the system, narrow band signal power levels received in the specified narrow frequency bands; determining, by the system, an adaptive threshold based on at least some of the narrow band signal power levels; detecting, by the system, a narrow band interferer according to the adaptive threshold, to obtain a detected narrow band interferer; responsive to a detection of the narrow band interferer, obtaining, by the system, identification information for a source of the narrow band interferer; and initiating, by the system, 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.
