MIMO技术在船舶通信平台的技术研究及仿真

Research on the MIMO technology for ship communication platform

在现有的船舶通信平台中,多输入输出系统(MIMO)平台已经得到广泛研究。但是在船舶MIMO通信系统中,由于海面噪声及多径干扰的影响,利用基于陆面无线通信的一些技术,如频分复用、多进制相移调制调解技术以及传统的信道编解码并不能满足通信系统对容错性能的要求。本文在研究了现有的MIMO通信系统的基础上,设计了一个两发射天线的MIMO船舶通信平台,通过特定的时空及信道编码及正交频分复用技术,较好地解决了海面噪声及多径干扰问题。

In the ship communication platform,MIMO communication system has been extensively researched. Because of the influence of sea surface noise and multipath interference,some technologies of wireless communication on land can＇t meet the requirements of marine communication system. At last,this paper use alamouti space time coding and frequency division multiplexing technology to design a two antenna MIMO ship communication platform.
