| 摘 要： | 在并行多双向中继通信系统中,提出了一种低复杂度的中断概率最优的中继选择策略,各个中继只需利用本地信道状态信息(CSI)进行分布式的选择.在Nakagami-m信道下分析了所提策略的中断概率性能,推导了系统中断概率的闭合表达式.仿真结果显示,该中继选择策略的中断概率性能在2种信道情况下均优于其他中继选择算法,且随着中继数的增加,所提策略可充分利用多中继分集提升系统中断概率性能.

| Abstract: | In the parallel multiple two-way relays communication systems,an outage-optimal relay selection scheme with low complexity is proposed,which is performed with only local channel state information(CSI) in a distributed way.In the Nakagami-m channel,the outage probability performance of the proposed scheme is ana-lyzed,and the closed expression of the system outage probability is also derived.Simulation results show that,the proposed relay selection scheme can outperform other relay selection algorithms under... |
