Abstract:Cognitive Radio has become an effective solution for the scarcity and the inefficient use of the spectrum. The performance of the cognitive radio (CR) system depends however on how well it can maximize the usage of the free bands without causing interference to primary users. The ability to detect the primary user in CR systems relies on Spectrum Sensing (SS). In this paper we propose a method to improve the performance of Energy Detection SS using Wavelet Denoising. Cooperative and non-cooperative sensing sce… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
