演示：用于高质量视频传输的自由空间光学统一平台
Demo: A Unified Platform of Free-Space Optics for High-Quality Video Transmission
摘要：
在本文中，我们研究了通过基于FPGA的自由空间光（FSO）通信系统原型的视频信号传输。我们使用一个信道仿真器，模拟湍流，闪烁和功率衰减的FSO信道和基于FPGA的实时原型处理发送和接收的视频信号。我们通过改变湍流的量和风速来改变信道仿真器的设置环境。在演示的最后，我们展示了通过我们的测试平台，即使是60 fps的4K超高清（UHD）分辨率视频也可以在高湍流和风速下成功传输。
英文摘要：
In this paper, we investigate video signal transmission through an FPGA-based free-space optical (FSO) communication system prototype. We use a channel emulator that models the turbulence, scintillation, and power attenuation of the FSO channel and the FPGA-based real-time prototype for processing transmitted and received video signals. We vary the setup environment of the channel emulator by changing the amount of turbulence and wind speed. At the end of the demonstration, we show that through our testbed, even 4K ultra-high-definition (UHD) resolution video with 60 fps can be successfully transmitted under high turbulence and wind speed.
