Estimation of Success Probability in Cooperative Spectrum Sensing over Fading Channel
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. While 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
imperfect channels. The optimal number of cooperative secondary users is estimated over fading channel. Simulation results
show that the variation of success probability with respect to channel imperfection.
