摘要

本文利用最大比值组合(MRC)技术分析了认知中继传输在中继节点和目的节点上的中断概率。在认知系统中，在主从网络之间的干扰链路没有完美信道状态信息(CSI)的情况下，给出了二次中继网络的精确中断概率。分析结果和相关的仿真结果表明，干扰功率的增加会降低副网的分集增益。

Receive diversity in cognitive relay transmission: Outage analysis

This paper analyses outage probability of cognitive relay transmissions using maximal ratio combining (MRC) technique at relay and destination nodes. In the cognitive system, an exact outage probability in the secondary relay network is formulated in the absence of perfect channel state information (CSI) of interference links between primary and secondary networks. The analytical results and related simulation ones show that an increase in interference power (from the primary network) reduces diversity gains in the secondary network.
