摘要：

We analyze the performance of a fully decentralized relay-selection method for the re-lay-assisted Cognitive Radio(CR) systems.The method requires no explicit communication among relay,assumes no prior knowledge of geometry.In particular,we assume that the frequencies chosen by the relay-assisted CR network overlapped with an active primary link.The proposed relay-selection scheme decreases the outage probability by considering both the channel scenario and the interference to the primary link compared with the non-cooperative transmission.Benefits of cooperative diversity are increased with the increased number of relays.
