Abstract (2. Language): 
Bu çalýþmada Yaygýn Spektrum iletiþim sistemlerinde karþýlaþýlan duraðan olmayan bozucu giriþlerin Anlýk Frekans kestirimine dayalý bir zaman-freakans maskeleme yöntemi ile giderilmesi konusu incelenmektedir. Alýnan bozulmuþ iþarete ait anlýk frekans kestirimi evrimsel spektrumdan elde edilebilmektedir. Önerilen algoritmanýn baþarýmý örnekler üzerinde gösterilmiþtir.
Abstract (Original Language): 
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.
