摘要

自由空间光（FSO）通信作为一种速率高、延迟低、带宽大及支持快速链路部署的有效传输技术，近年来在面向大数据传输的无线通信领域日益受到业界重视。但是，FSO信号链路的通信性能易受天气条件和大气状态（尤其是大气湍流）的影响，从而导致信号收发质量及系统传输性能恶化。为提升FSO通信系统的收发及传输性能，近年来研究人员已开始在FSO通信系统中应用若干先进机器学习算法来优化信号检测和信道建模的过程，并取得了新的研究进展。文章综述了FSO通信系统中在信号检测、信道估计和辅助光学补偿等方面应用典型机器学习算法的研究情况，对比分析了使用不同典型机器学习算法的应用特点，并探讨了FSO通信系统中应用机器学习算法的未来发展趋势。

Abstract

Free-Space Optical (FSO) communication

as an effective transmission technology with high speed

low latency

large bandwidth

and support for rapid link deployment

has been increasingly valued in the field of wireless communication aimed at big data transmission in recent years. However

the communication performance of FSO signal link is susceptible to weather conditions and atmospheric states (especially atmospheric turbulence)

resulting in degradation of signal reception and transmission quality as well as system performance. In order to enhance the reception

transmission

and overall performance of FSO communication systems

researchers have begun to apply various advanced machine learning algorithms to optimize the signal detection and channel modeling processes in FSO communication systems. In this article

the research progress of applying typical machine learning algorithms in FSO communication systems in signal detection

channel estimation

auxiliary optical compensation

and other aspects are reviewed. We compare and analyze the application characteristics of different typical machine learning algorithms

and discuss the future development trends of applying machine learning algorithms in FSO communication systems.
