Abstract :
In this paper, we propose a cooperative spectrum sensing scheme in which the secondary users can exchange their sensing data by using the underlay approach in the cognitive radio network. The bandwidth issue in soft combination for cooperative spectrum sensing is considered. We further invest-tigate the interference probability between secondary network and primary network.
