Abstract

Cooperation among secondary users improves the spectrum sensing performance by allowing local decisions measured over independent sensing channels. This reduces the miss detection and false alarm probabilities. Most of the works in cooperative spectrum sensing techniques assume perfect channels between the cooperating secondary users. In this paper, we considered the effect of imperfect channels. Total error rate and success probabilities are calculated for an additive white Gaussian noise channel and a Rayleigh fading channel. The optimal number of cooperative secondary users is estimated over nonfading and fading channels. Simulation results show the variation of success probability with respect to channel imperfection for different number of secondary users. This is useful for identifying the unutilized spectrum.
