摘要
水下光通信是一种新兴且可行的水下通信技术,近年来发展迅速。建立高性能、实用的水下光通信系统,需要从器件到系统,从内部调制到外部环境的综合考虑和优化设计。文章从水下光通信系统的发射机和接收机、调制格式和水下信道等方面综述了水下光通信目前面临的难题,对提高水下光通信的通信距离、通信速率和通信稳定性3个方面关键技术进行了分类和总结,并提出了可以实现的解决方法,为后续系统设计和实验研究提供了参考。
Underwater optical communication is a new and feasible underwater communication technology,which has developed rapidly in recent years.To build a high-performance and practical underwater optical communication system,it is necessary to consider and optimize the design from the device to the system,from the internal modulation to the external environment.This paper summarizes the current problems of underwater optical communication from the aspects of underwater optical communication system transmitter and receiver,modulation format and underwater channel.The paper also classifies and summarizes the three key technologies of improving underwater optical communication distance,communication rate and communication stability,and gives the possible solutions.It provides reference for the follow-up system design and experimental research.
