摘　　要：文章选用多中继、多输入多输出(MIMO)双跳中继网络系统,在部分中继选择(PRS)和最佳发射天线/最大比合并(TAS/MRC)的传输策略下,考虑源端、中继端和目的端三个节点均存在硬件损伤(HI),且对于系统性能进行了分析。在分析标准上,除常用的中断概率之外,进一步选用了系统吞吐量和能量效率,对整个性能进行综合性衡量。最后给出了Monte-Carlo仿真结果,对理论推导予以佐证。In the consideration of Hardware Impairments（HI）, the performance analysis of the Multiple-Input-Multiple-Out（MIMO） dual-hop multiple relay networks was conducted, in which the strategy of Transmit Antenna Selection/Maximal Ratio Combining（TAS/MRC） and Partial Relay Selection（PRS） were adapted for communication. Assuming that all the three nodes were under Hardware Impairments（HI）, the closed-form and asymptotic expressions of the out- age probability were derived. To get some further insights, the system throughput and energy ef- ficiency were also selected as analysis metrics, and then the closed-form expressions were also given. Finally, the Monte-Carlo simulation results validate the correctness of theory.
