摘要
舰船远程航行过程中的无线通信依靠海事卫星和GPRS技术,近年来,5G技术发展越来越成熟,基于5G的舰船远程通信系统开发成为一项热点。本文设计一种舰船远程航行信息交互系统,对系统的构成和关键技术环节进行研究,包括5G通信信号的调制技术、基于神经网络算法的5G调制信号识别技术等。最后,结合Simulink软件进行了舰船远程航行信息交互系统的5G通信性能测试。
The wireless communication in the course of long-range navigation depends on maritime satellite and GPRS technology,in recent years,the development of 5G technology is more and more mature,the development of ship long distance communication system based on 5G has become a hot research.In this paper,a kind of ship long-distance navigation information interaction system is designed,and the composition and key technical links of the system are studied,including the modulation technology of 5G communication signal,the recognition technology of 5G modulation signal based on neural network algorithm,and so on.Finally,combined with simulink software,the 5G communication performance test of ship long-distance navigation information interaction system is carried out.
