摘　　要：为了更加符合中继信道的实际情况,采用Nakagami分布建模无线信道,推导了非再生中继方式下多输入多输出(MIMO)中继系统中断概率的闭合表达式.通过仿真分析了信道衰落参数和天线配置对系统中断性能的影响.仿真结果表明,在非再生MIMO中继系统中,第1跳链路的信道质量对系统的中断性能起主要影响.Considering that it is more suitable to model relay channel with Nakagami, closed-form expressions of outage probability is derived for multiple-input multiple-output （MIMO） relaying channels in two-hop nonregenerative relay networks operating over Nakagami fading channels. The effects of fading parameters and antenna configuration on the overall system performance are analyzed and discussed with assistance of representative numerical examples. Simulation shows that the channel quality of the first hop link in nonregenerative MIMO relaying system adds major influence on outage performance.
