摘要：Opportunistic unlicensed access to the (temporarily) unused frequency bands across the licensed radio spectrum is currently being investigated as a means to increase the efficiency of spectrum usage. Wireless communication, in which a transmitter and receiver can detect intelligently communicate channels that are in use and those which are not in use are known as Cognitive Radio, and it can move to unused channels. Dynamic spectrum access is a promising approach to make less severe the spectrum scarcity that wireless communications face now. It aims at reusing sparsely occupied frequency bands and does not interfere to the actual licensees. The ability to reliably and autonomously identify unused frequency bands is envisaged as one of the main functionalities of cognitive radios. In this paper, it is proposed that an augmented spectrum sensing algorithm in cognitive radio systems and calculate the optimal value nopt to minimize the error rate in cooperative spectrum sensing
