  • 摘要: 随着无人机(UAV)系统的规模持续扩大以及对更高通信速率的需求增长,UAV光移动通信(UAV-OMC)已经成为一个有前景的技术方向。然而,传统的UAV-OMC难以支持多UAV之间的通信。该文基于光学智能反射表面(OIRS)技术,提出一个适用于UAV群的分布式OMC系统。通过在特定的UAV上设置OIRS,利用OIRS将光信号从单个UAV节点扩散到多个UAV节点。这一系统在保留UAV-OMC系统的高能效和高速度的同时,能够支持分布式UAV群的通信。对所提出的系统进行了数学建模,考虑了一系列现实因素,如OIRS的光束控制、UAV之间的相对运动和UAV的抖动等,这些因素都符合实际系统的特点。此外,该文还推导出了系统的误比特率(BER)和渐进中断概率的闭式表达式。基于理论分析和模拟结果,讨论了各个参数和系统设计的影响。
