在主用户频谱共享约束条件下，推导了在目的端配置单个放大转发（AF）中继和选择合并接收机的认知双跳中继网络的精确中断概率（OP）。易处理的封闭形式的OP容易使系统性能的评估，这表明在认知无线电网络中使用中继的频谱共享方法的意义。数值算例验证了所提出的分析方法的有效性。
The exact outage probability (OP) of cognitive dual-hop relay networks equipped with a single amplify-and-forward (AF) relay and a selection combining receiver at the destination is derived under spectrum sharing constraint on a primary user. The tractable closed-form OP readily enables evaluation of system performance, which indicates the significance of using a relay in cognitive radio networks with a spectrum sharing approach. The proposed analysis is validated by numerical examples.
