推导了认知无线电双跳放大转发（AF）中继网络中断概率（OP）的精确闭式表达式。以初等函数的形式给出的OP的易处理的表达容易使得能够评估主用户对次级系统性能的影响。它已被证明，使用AF中继显着提高认知无线电网络的性能相比，其直接传输对应。
The exact closed-form expression for the outage probability (OP) of cognitive radio dual-hop amplify-and-forward (AF) relay networks is derived. The tractable expression of the OP, given in the form of elementary functions, readily enables evaluating the effect of primary users on the secondary system performance. It has been shown that the use of AF relaying significantly improves the performance of cognitive radio networks compared to its direct transmission counterpart.
