AI 中文摘要
本文提出了一种由光波信息与功率同时传输（SLIPT）赋能的、光可重构智能表面（ORIS）辅助的地对无人机自由空间光（FSO）通信系统。为克服基于FSO的SLIPT系统的视距（LoS）限制，引入ORIS将激光束反射向非视距无人机接收器。对包括大气损耗、湍流衰落、指向误差和无人机悬停引起的到达角波动等组合信道特性进行建模分析，推导了收集能量、中断概率和符号错误率（SER）的闭式表达式。数值结果表明，集成ORIS可提高能量收集（EH）效率，同时保持可控的中断和SER性能。
英文摘要
This paper proposes an optical reconfigurable intelligent surface (ORIS)-assisted ground-to-unmanned aerial vehicle (UAV) free-space optical (FSO) communication system empowered by simultaneous lightwave information and power transfer (SLIPT). To overcome the line-of-sight (LoS) limitation of FSO-based SLIPT systems, we introduce an ORIS that reflects the laser beam towards a non-LoS UAV receiver. We model and analyze the combined channel characteristics, incorporating atmospheric loss, turbulence-induced fading, pointing error, and angle-of-arrival fluctuations due to UAV hovering. We derive closed-form expressions for harvested energy, outage probability, and symbol error rate (SER). Numerical results show that integrating ORIS improves EH efficiency while maintaining manageable outage and SER performance.
