摘要

本文对两架无人机之间太赫兹(THz)链路的中断概率进行了分析和数值研究。建立了考虑多径衰落、到达角和指向误差共同影响的复合衰落统计模型。利用推导出的中断概率表达式来说明忽略无人机天线方向波动时的误导结果。此外，数值研究了在阈值中断概率约束下，天线半功率波束宽度对最大可达链路长度的影响。将解析结果与蒙特卡罗(MC)模拟结果进行比较，验证了推导式的正确性。

Outage Performance of Inter-UAVs THz-Link under Composite Fading Channels

In this letter, outage probability of terahertz (THz) link between two unmanned aerial vehicles (UAVs) is analytically and numerically investigated. Composite fading statistical model is developed considering joint effects of multipath fading, angle of arrival (AoA), and pointing-errors. The derived expression for outage probability is used to illustrate the misleading results in case of neglecting UAV antenna orientation fluctuations. In addition, effect of antenna half power beam width (HPBW) on maximum achievable link length under constraint of threshold outage probability is numerically investigated. Derived expression is validated by comparing analytical results with Monte Carlo (MC) simulation and they show high degree of agreement.
