摘要

非视距（NLOS）水下无线光通信（UWOC）主要利用空气—海水界面反射或海水中微粒对光的散射进行通信，可以有效地解决视距（LOS）UWOC的链路对准问题。文章总结了NLOS UWOC技术在信道模型、模拟仿真和实验研究方面的研究进展。目前，国内外学者主要探索了水质、波浪、湍流、调制技术和收发端配置等因素对NLOS UWOC链路性能的影响。很少有学者研究复杂的水动力和水质综合因素、光源的非线性、探测器的非线性、灵敏度以及噪声等对NLOS UWOC性能的影响以及有效解决方案。为此，未来需要展开更加深入的信道模型、仿真和实验研究，从而推动NLOS UWOC技术的发展。

Abstract

Non-Line-of-Sight (NLOS) Underwater Wireless Optical Communication (UWOC) is mainly realized through the air-seawater interface reflection or the scattering of light by particles in seawater. It can effectively solve the link alignment issues of Line-of-Sight (LOS) underwater wireless optical communication. This paper summarizes the research progress of NLOS UWOC technology in the aspects of channel model

simulation and experiment. At present

scholars mainly explore the effects of water quality

wave

turbulence

modulation technology

receiving and sending terminal configuration on the performance of NLOS UWOC link. Few scholars have studied the effects of complex hydrodynamic and water quality factors

non-linearity of light source

non-linearity

sensitivity and noise of detector on the performance of NLOS UWOC and effective solutions. Therefore

it is necessary to carry out more in-depth channel model

simulation and experimental research in the future

so as to promote the development of NLOS UWOC technology.
