摘要:In this paper, the analysis model which suites to Cognitive Radio (CR) communication together with amplify-and-forward cooperative communication systems where cognitive users can act as cooperative diversity relays to the licensed users based on average Channel State Information (CSI) is presented. Firstly, the model of the cooperative and cognitive radio system is given. Then, the transmitting protocols both in physical and Media Access Control (MAC) are described in brief. Thirdly, the expressions of the outage performance are derived both for licensed user and cognitive user in ideal cognitive radio environment for simplification where there are no detection errors and interference between licensed user and cognitive user under Reighlay fading channel environment. Further study which suits for real environment can be discussed in the future. In the end, computer simulation is carried out to prove the above theory analyses.
