Abstract
In this paper we focus on spectrum sensing in cognitive radio to sense the presence of primary user. Cognitive users are allowed to utilize the licensed spectrum when the primary user is absent. Here Energy detection technique is considered best for spectrum sensing. Additive White Gaussian Noise (AWGN) and Rayleigh fading channel is considered for local spectrum sensing. To enhance the detection capability of primary user, the data of neighboring cognitive radios is collaboratively collected at global sensing, and a decision is made depending upon the unanimous decision of all the cognitive radios. The final decision may differ depending upon level of co-operation between the neighbors. Keywords—spectrum sensing;cognitive radio;Energy detection;
