摘要：

Cognitive radio (CR) plays a key role in upcoming 5-G wireless technology. The main task of CR technology is to detect the presence of licensed user or primary user (PU) for effective utilization of the spectrum. In this paper, fist we study the non-cooperative spectrum sensing with a variation in time-bandwidth product over a non-fading (additive white Gaussian noise, AWGN) channel and fading channels (Rayleigh and Rician). Analytical and simulation frameworks are presented over fading and non-fading channels. Second, we consider voting rule for hard decision combining in cooperative spectrum sensing and the impact of time-bandwidth product over an AWGN and fading channels is investigated. An optimal decision fusion rule is investigated with respect to time-bandwidth product that minimizes the total sensing error in cognitive radio network.
