摘要: 与传统视距光通信不同,紫外光通信能够实现非视距通信,广泛地应用于视距链路受阻的场景,近年来工业互联网的高速发展催生了工业设备间大容量灵活组网通信的需求,这给紫外光通信带来了新机遇。为推动紫外光通信的实用化研究,阐明了紫外光通信的主要应用场景,概述了紫外光通信的研究现状,介绍了硬件试验、信道模型、信道估计与检测、空间分集技术等关键技术,展望了紫外光中继与双工通信、紫外光传感网络和非视距定位技术等未来发展方向和相应挑战。

关键词: 紫外光通信, 非视距通信, 非视距定位

Abstract: Different from conventional line-of-sight optical communications, ultraviolet communications can achieve non-line-of-sight communication, and thus it can be widely used in scenarios where line-of-sight links are unavailable. In recent years, the rapid development of the industrial internet spurs the demands of communications among industrial equipment with high capacity and flexible networking, which brings new opportunities for ultraviolet communications. To propel the practical research of ultraviolet communications, the major applications and the state-of-the-art developments on ultraviolet communications are investigated, especially in crucial techniques such as hardware experiments, channel modeling, channel estimation and detection. Spatial diversity technologies are introduced. The future research directions and challenges of ultraviolet communications are also envisioned, including ultraviolet relay and duplex communication, ultraviolet sensor networking, and non-line-of-sight positioning.

Key words: ultraviolet communication, non-line-of-sight communication, non-line-of-sight positioning
