摘要: 针对认知无线电通信系统的协作通信问题，本文提出一种基于解码转发和接收信噪比最大化的最优中继集合选择方案，同时理论推导出基于该最优中继集合选择方案的认知无线电通信系统的中断概率，并对传统直接通信(direct)方案，随机选择中继方案和本文提出的方案进行了性能仿真，仿真表明本文提出的方案能有效降低认知无线电系统的中断概率。
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.
