An encouraging technology that grabs the clash between spectrum scarcity and underutilization is cognitive radio (CR), spectrum sensing is the main task of cognitive radio. Cooperative spectrum sensing overcomes the adverse effect of shadowing and multipath. In this paper, the optimization of cooperative spectrum sensing has been proposed in order to optimize the overall performance by variation of SNR. In this optimization process, three parameters; spectrum sensing technique used locally, SNR and the number of users have been considered. Decision made by all the users is sent to the fusion center which estimate the final presence or absence of primary user.
