Abstract
A method for suppressing radio interference via active filtering and modulation detection includes receiving, at a radio, a signal, and digitizing the signal to generate a digitized signal. The method also includes processing the digitized signal to extract a carrier frequency of the digitized signal and one or more signal characteristics of the digitized signal. Based on the carrier frequency of the digitized signal and the one or more signal characteristics of the digitized signal, the method further includes determining, using a symmetry filtering model, that the one or more signal characteristics of the digitized signal shift linearly with respect to the carrier frequency of the digitized signal, and filtering, using a filter, the signal.
