In this paper, we suggest the use of Reconfigurable Intelligent Surfaces (RIS) for hybrid Radio Frequency (RF) Visible Light Communications (VLC). The signal is transmitted from a transmitter T to a relay C using RIS. RIS is implemented as a transmitter or a reflector between T and C. The relay node C decodes the received signal and transmits it to the receiver R using a VLC link. The proposed VLC/RF communications using RIS offers 20–45 dB gain with respect to conventional RF/VLC when the number of reflectors N is varied from \(N=16\) to \(N=256\).

使用可重构智能表面的混合 RF/VLC 通信

在本文中，我们建议将可重构智能表面 (RIS) 用于混合射频 (RF) 可见光通信 (VLC)。信号从发射器T使用 RIS传输到继电器C。RIS 被实现为T和C之间的发射器或反射器。中继节点C对接收到的信号进行解码并使用VLC链路将其发送到接收器R。当反射器的数量N从\(N=16\)到\(N=256\)变化时，建议使用 RIS 的 VLC/RF 通信相对于传统的 RF/VLC 提供 20–45 dB 的增益。
