水声通信及组网的现状和展望

Study on the Status and Prospect of Underwater Acoustic Communication and Networking

水声通信是海洋中无线信息传输的主要技术手段。水声通信技术在海洋环境监测、水下航行器/载人潜水器作业等方面有着广泛应用。同时,水声信道传输状态多变、海洋作业环境恶劣,对通信算法和设备可靠性有较高要求,水声通信及组网成为目前的研究热点。文中面向海洋环境监测领域,从水声通信物理层技术、网络技术及组网应用等方面进行介绍,并对未来技术趋势进行展望。

Underwater acoustic communication is the main wireless information transmission technique in the ocean. It is widely used in ocean environment observation and operations of underwater vehicles and manned submersibles. Meanwhile, the adverse operation conditions at sea and rapidly changing transmission state of underwater acoustic channels require high reliability of the communication devices and high performance of the communication algorithms. Underwater acoustic communication and networking has become a research focus. This paper concentrates on the field of marine environment monitoring, introduces the physical layer technology,network technology and networking application of underwater acoustic communication, as well as discusses the development trend of underwater acoustic communication and networking technology.
