为提供在火车和 trackside 网络之间的可靠、高的数据率通讯的高速度的铁路(高速阅读器) 的无线通讯是一项挑战性的任务。无线通讯交通能每高速度的火车象 65 Mbps 一样高,这被估计。接着,如此的高速阅读器通讯系统和标准的发展为高速阅读器繁殖隧道要求精确模型。这篇文章在最近的年里提供存在高速阅读器隧道测量运动的概述。特别地,在各种各样的高速阅读器情形的一些重要测量和当模特儿的结果例如旱桥和 U 字形的沟(USG ) ,简短被描述并且分析。另外,我们考察鸣方法的一条新奇隧道,它能高度在高速阅读器环境改进测量效率。
Wireless communication for high-speed railways (HSRs) that provides reliable and high data rate communi- cation between the train and trackside networks is a challenging task. It is estimated that the wireless communication traffic could be as high as 65 Mbps per high-speed train. The development of such HSR communications systems and standards requires, in turn, accurate models for the HSR propagation channel. This article provides an overview of ex- isting HSR channel measurement campaigns in recent years. Particularly, some important measurement and modeling results in various HSR scenarios, such as viaduct and U-shaped groove (USG), are briefly described and analyzed. In addition, we review a novel channel sounding method, which can highly improve the measurement efficiency in HSR environment.
