摘要
针对基于光电混合架构的无人机中继通信系统下行链路多用户传输场景，提出了一种基于统计信道状态信息的波束成形方案，并进一步分析了系统的中断概率。在该混合架构中，基站—无人机链路和无人机—用户链路采用自由空间光技术和射频传输完成通信过程。在已知RF链路统计信道状态信息的情况下，首先提出了一种波束成形方案以抑制用户间干扰，实现所有用户同时通信，提升了系统的频谱效率。然后，在自由空间光链路和射频链路分别服从 Gamma-Gamma 分布和 Nakagami-m 分布的条件下，推导出了系统中断概率的闭合表达式。进一步，得到了高信噪比条件下中断概率的渐进表达式，获得了系统的分集度。最后，仿真结果验证了理论分析的正确性以及所提方案的优越性。
Abstract
A mixed free space optical (FSO)-radio frequency (RF) transmission was studied in the multiuser unmanned aerial vehicle (UAV)-aided terrestrial network.Specifically
a novel beamforming (BF) scheme was proposed based on the available statistical channel state information (CSI)
and the outage performance of the considered system was analyzed.In this mixed framework
the link between the base station and the UAV employs the FSO technology
while aerial-terrestrial links use RF technology.To achieve the space division multiple access (SDMA) in RF links.First of all
the available statistical CSI was proposed
and a novel beamforming (BF) scheme was proposed to suppress the inter-user interference so that all the users can be served simultaneously.Then
based on the assumption that the FSO and RF links follow the Gamma-Gamma fading and Nakgami-m fading respectively
an analytical expression was derived for the outage probability (OP) of the considered system.Furthermore
the asymptotical OP expression in high signal-to-noise ratio regime was presented to evaluate the achievable diversity order.Finally
numerical results were given to confirm the validity of our theoretical analysis and the superiority of the proposed scheme.
