This paper considers the cooperative spectrum sensing (CSS) in a cognitive radio (CR) network, where K secondary users (SUs) are used to determine the primary user's (PU's) signal using the m-out-of-K rule. In CR networks, the SUs must opportunistically utilizes to the PU's channel without affecting the quality of service of the PU. Therefore, we aim to optimize the m value and the K value of the m-out-of-K rule to achieve the maximum channel throughput of the CR network (throughput of the PU plus throughput of the secondary network) under sufficient protection to the PU. The results are illustrated using the energy detector.
