Energy detection is a challenging problem in several applications in cognitive radio communications. In cognitive radio the spectrum is under-utilized. Proper employment of these channels are needed. This work determines the various effects of multipath fading on energy detection and their performance evaluation. For detecting energy Rayleigh channels and additive white real Gaussian signal and noise is used. It has been observed that detection performance is degraded by increasing multipath and cascading channels. Further the optimization of cooperative spectrum sensing with energy detection to minimize the total error rate is considered. An optimal voting rule for optimal value of cognitive radios is used. The different error levels are founded by varying the SNR values to find the optimal number of CRs for minimizing the error levels.
