Abstract

Currently, ultraviolet (UV) communication is proposed for use in unmanned aerial vehicle (UAV) communication, while the efficient transmission of images with limited bandwidth has posed a persistent challenge. This paper introduces a light-emitting diode-based UV communication system combined with semantic compression for image transmission. The experimental results show that the proposed semantic UV communication (SUC) system could transform a 7.19 MB image to a file of approximately 304 kB with the aid of deep learning, effectively reducing the bandwidth required for transmission. In addition, by jointly designing the encoding and modulation process and incorporating the interference light signals from the receiver’s detector into the joint coding-modulation (JCM) system for training, the resulting modulation strategy is matched with the actual transmission conditions. The experimental results demonstrated that the system could work well over 100 m while sending images with good quality in the face of error bits interference.

语义紫外通信系统有限带宽下百米图像传输的实验研究

目前，紫外（UV）通信被提出用于无人机（UAV）通信，但如何在有限带宽下有效传输图像一直是一个挑战。介绍了一种结合语义压缩的基于发光二极管的紫外通信系统。实验结果表明，所提出的语义紫外通信（SUC）系统可以通过深度学习将7.19 MB的图像转换为约304 kB的文件，有效地降低了传输所需的带宽。此外，通过联合设计编码和调制过程，将接收机探测器的干涉光信号纳入联合编码-调制（JCM）系统进行训练，使调制策略与实际传输条件相匹配。实验结果表明，该系统可以在100米以上的距离内，在误差位干扰下，保持良好的图像传输质量。
