© 2011 KICS. In this paper, we analyze the spectrum-sensing performance of a cooperative cognitive radio (CR) network consisting of a number of CR nodes and a fusion center (FC). We introduce the «log-average-SNR ratio» that relates the average SNR of the CRnode- FC link and that of the primary-user-CR-node link. Assuming that the FC utilizes theK-out-of-N rule as its decision rule, we derive exact expressions for the sensing gain and the coding gain - parameters used to characterize the CR network performance at the high SNR region. Based on these results, we determine ways to optimize the performance of the CR network.
