Abstract
A communication device may include a communication interface configured to receive signals and a controller configured to: receive an input signal based on the received signals; perform transform operations on the input signal to generate a spectral periodogram of the input signal; calculate spectral vector powers for each bin of a plurality of bins of the spectral periodogram; determine a median spectral power for a selected range of bins of the plurality of bins; generate a median-scaled spectral density vector based on the median spectral power and a reference spectral density of an expected signal; calculate a detection threshold vector based at least in part on the median-scaled spectral density vector; and identify one or more interference-including bins of the plurality of bins of the spectral periodogram by comparing the spectral vector powers for each bin of the plurality of bins to the detection threshold vector.
