A Best Relay Set Selection Scheme for Cooperative Transmission in Cognitive Radio Network
Abstract: In this paper, a best relay set selection scheme based on Decode and Forward and received SNR maximization is proposed for cooperative communication in Cognitive Radio system, and the closed-form expression of outage probability based on the proposed scheme is derived. Further-more, the proposed scheme is compared with traditional direct communication scheme and the random relay selection scheme in terms of outage probability through numerical experimentation. Numerical results illustrate that the proposed scheme can greatly decrease outage probability.
