Abstract:
1. A method, comprising: analyzing, by a system comprising a processor, a wide frequency band with respect to signal power levels in a plurality of specified different narrow frequency bands; detecting, by the system, a plurality of different narrow band signal power levels received in the plurality of specified different narrow frequency bands; identifying, by the system, a selected narrow frequency band of the plurality of specified different narrow frequency bands having a selected narrow band signal power level higher than other narrow band signal power levels of the plurality of different narrow band signal power levels; determining, by the system, an average composite wideband power level from the plurality of different narrow band signal power levels without considering the selected narrow band signal power level of the selected narrow frequency band; determining, by the system, an adaptive threshold based on the average composite wideband power level; detecting, by the system, according to the adaptive threshold, interference associated with a plurality of channels in the wide frequency band, to obtain detected interference; and configuring, by the system, a filter bandwidth of a variable-bandwidth filter according to the detected interference to suppress the interference.
