摘　　要：认知中继网络是现在研究的一个热点问题,然而硬件的不完美会引起系统的硬件损伤。硬件损伤对系统的性能有着重大的影响,尤其是对中断概率具有重大的影响。文章主要研究的是硬件损伤条件下的认知中继网络性能问题,首先研究硬件损伤对于认知中继网络的中断概率的影响,其次将具有硬件损伤的认知中继网络和无硬件损伤的认知中继网络进行了对比,并得到了必要的结论,最后给出了必要的仿真和讨论来说明硬件损伤对于认知中继网络有很大的影响。Cognitive relay network is a hot topic in current research. However, imperfect hardware will cause hardware impairments. Hardware impairments have serious impact on the system performance, especially the outage probability. In this paper, the cognitive relay network performance under hardware impairments was mainly analyzed. Firstly, the outage probability of cognitive network was analyzed. Secondly, the network with hardware impairments was compared with the network under ideal hardware. Some useful conclusions were derived. Finally, some necessary simulations and discussions were given, which show the correctness of this paper.
