Abstract

In this paper, we consider the problem of jammer excision in Spread Spectrum (SS) communication systems. We apply a time--frequency mask obtained by the instantaneous frequency (IF) estimate of the interference signal. The IF of the received signal is estimated from an Evolutionary Spectrum. Performance of our algorithm is presented by means of examples.
