论文摘要
光学重新配置智能表面（ORIS）是一种新兴技术，可以通过精确调整信号的反射和形状，通过大量的被动反射元素来实现可重新配置的光学传播环境。在本文中，我们研究了由Oris辅助的双跳型混合射频（RF）和自由空间光学（FSO）通信系统的性能。通过共同考虑ORIS，RF通道，大气湍流和指向误差的物理模型，已经得出了系统确切的中断概率的闭合溶液，渐近中断概率和BER得出了。通过数值结果表明，推导结果是准确的，并且与Oriss的RF-FSO链接显示出比传统的RF-FSO链接稍差。根据理论分析和仿真结果，已经讨论了每个参数的系统设计和效果。
Optical reconfigurable intelligent surface (ORIS) is an emerging technology that can achieve reconfigurable optical propagation environments by precisely adjusting signal's reflection and shape through a large number of passive reflecting elements. In this paper, we investigate the performance of an ORIS-assisted dual-hop hybrid radio frequency (RF) and free space optics (FSO) communication system. By jointly considering the physical models of ORIS, RF channel, atmospheric turbulence, and pointing error, the closed-form solutions of the system's precise outage probability, asymptotic outage probability and BER have been derived. It is shown through numerical results that the derivation results are accurate and the RF-FSO links with ORISs show a slightly worse performance than the traditional RF-FSO links. Based on theoretical analysis and simulation results, the system design and effect of each parameter have been discussed.
