软件无线电技术在海面通信信号处理中的实现

摘要

In maritime communication system,because of the complexity of maritime climate and sea noise,it is difficult to use the inherent hardware to achieve all signal processing functions. Therefore,it is particularlyimportant to build an integrated platform to achieve maritime wireless communication functions. This paper first analyzes the existing software radio platform technology and maritime communication signal characteristic,and the proposed signal adjusting mediation and spatial analysis method based on software radio technology.%在海上通信系统中，由于气候环境及噪声的复杂性，对通信信号的调制调解方式很难利用固有的硬件处理方式来统一实现，并且由于海上潮湿的气候环境及海风风浪等浸蚀，对电子硬件设备的伤害较陆地严重，所以构建统一的平台来实现海上无线通信功能尤为重要。本文在研究现有软件无线电平台技术及海上通信信号特征的基础上，提出基于软件无线电技术的海上通信信号调整调解及信号空间分析的方法，最后给出基于软件无线电的海上通信系统模型并进行仿真实验。
