Abstract

In this paper, we considered a cooperative spectrum sensing over fading and non-fading channels. We proposed a model of a Rayleigh fading channel and a non-fading additive white Gaussian noise channel. Total error rates and the optimal number of cooperative secondary users over the non-fading channel and the success probability over the fading channel are calculated and the simulation results plotted. The simulation results convey that the optimal number of secondary users is five in both cases. We hope that our results will be useful in improving energy efficiency in identifying the unutilized spectrum.
