Performance of Cooperative Spectrum Sensing for Different Number of CR users in Cognitive Radio

Mohammad Alamgir Hossain, Shahoreare Ahmed, Md. Shamim Hossain, Md. Ibrahim Abdullah

Abstract: We have studied the performance of cooperative spectrum sensing for different number of CR users in cognitive radio over non-fading channel AWGN and fading channels such as Rayleigh and Nakagami. This paper presents a simulation comparison of these fading channels based on fusion OR-rule. We observe that spectrum sensing for different number of CR users is harder in presence of Rayleigh and Nakagami fading than non-fading AWGN channel. It also shows that spectrum sensing gives better performance when more number of CR users is cooperated.
