摘要:

基于Nakagami衰落信道推导了非再生中继方式下采用发射天线选择/接收最大比合并(TAS/MRC)技术的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,第一跳链路的信道质量对系统的中断性能起主要影响作用。

Abstract:

Closed-form expressions of outage probability is derived for multiple-input multiple-output (MIMO) relaying channels with transmit antenna selection/ maximal-ratio combining in two-hop nonregenerative relay networks operating over nakagami fading channels. The effects of fading parameters and antenna con?guration on the overall system performance are analyzed and discussed through representative numerical examples. Simulation results show that channel quality of the first hop link in nonregenerative MIMO relaying system plays a major influence on outage performance.
