海上宽带移动无线信道建模研究
Research on Broadband Mobile Wireless Channel Modeling at Sea Surface
Abstract
宽带移动无线网络几乎覆盖了地球上大多数的陆地,而海上宽带移动通信极大地落后于陆地无线通信,更多只能依靠昂贵的卫星进行通信。随着技术的发展,海上宽带无线通信系统的搭建有望实现。海上无线宽带信道建模是搭建海上宽带无线通信系统的基础。目前已有大量的针对海上无线信道测量工作展开。无线信道的测量工作耗时漫长,测量环境受限,无法准确地描述多变的海上无线信道。而通过仿真建模,可以快速模拟各种移动场景,得到较为精确的信道模型,修正经验模型的误差,因此对海上无线信道的仿真建模同样具有重要的意义。 借助于升空平台,可实现对海上无线网络的覆盖。本文模拟海上升空平台与船只通信的场景,对此场景下的海上无线信道特性进行... With the mobile wireless network has covered most of the land on the earth, there are still lack of network coverage in the important channels and ocean operating areas. The broadband mobile communications are still relatively backward at seas. In most marine cases, only expensive satellite communications can be used. Thanks to the progress technology, it is expected to achieve wireless network co...
