Double Threshold Energy Based Spectrum Sensing with Copulas

ArticleAçık Erişim

Özet

As it is known, Energy based detection is widely used in Cognitive Radio and radar systems. In order to reduce the disruptive effects of wireless channels, Energy based sensing method has been used with different combinations. In this study, a new spectrum sensing method is proposed by combining the dual threshold energy based sensing method with Copula functions. The spectrum sensing model is given for the proposed method and the sensing method is explained with theoretical analysis. For simulation studies, OFDM based communication system was used under Rayleigh fading channel. Performance analysis of the proposed method was compared with traditional Energy based detection (both single and double threshold) and a noticeable increase in performance was observed. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
