Abstract
A method and apparatus for detecting a jammer comprising sampling an input signal; downconverting and sampling the input signal to generate a sampled downconverted (SD) input signal; comparing the sampled input signal to a wideband threshold THWB, and comparing the SD input signal to a narrowband threshold THNB; generating a wideband (WB) interrupt signal based on the comparison to the THWB, and generating a narrowband (NB) interrupt signal based on the comparison to the THNB; and generating a composite interrupt signal based on at least one of WB interrupt signal and NB interrupt signal. In one aspect, the apparatus comprises a wideband jammer detector for generating a WB interrupt signal to indicate a wideband jammer; a narrowband jammer detector for generating a NB interrupt signal to indicate a narrowband jammer; and interrupt logic for generating a composite interrupt signal based on one of WB interrupt signal and NB interrupt signal.
