In this paper, we propose a new wireless transmission technique using Reconfigurable Intelligent Surfaces (RIS) for hybrid RF/FSO communications. The signal is transmitted on two hops. The first hop uses Free Space Optical (FSO) communication while the second hop is based on Radio Frequency communications throughput RIS. The proposed RF/FSO communications using RIS offers 25–50 dB gain with respect to conventional RF/FSO. We derive the throughput at the packet level while previous studies analyze the symbol or bit error probabilities. The analysis is valid when RIS is used as transmitter or reflector.

在存在指向性错误的情况下，通过可重新配置的智能表面进行混合RF / FSO通信

在本文中，我们提出了一种使用可重配置智能表面（RIS）进行混合RF / FSO通信的新无线传输技术。信号在两跳上传输。第一跳使用自由空间光（FSO）通信，而第二跳基于射频通信吞吐量RIS。与传统的RF / FSO相比，使用RIS提出​​的RF / FSO通信可提供25–50 dB的增益。我们在数据包级别导出吞吐量，而先前的研究则分析了符号或误码率。当RIS用作发送器或反射器时，该分析有效。
