| 摘 要： | 高速铁路的发展要求与之配套的车地宽带无线通信系统得到相适应发展。一方面为乘客提供通信服务,除基本语音服务外,宽带数据业务的需求呈上升趋势;另一方面为保障列车安全运行,列车关键部件的大量实时状态信息需要及时传输到地面监控中心。因此,构建适应高铁环境的宽带无线接入系统势在必行。高铁无线信道模型是通信系统设计的基础,本文以高速铁路宽带无线接入为应用场景,分析高铁无线信道测量的特殊性,讨论经典信道测量方法和设备在高铁场景下的优缺点,研究了基于无线蜂窝的高铁宽带无线信道的测量方法。

| Abstract: | High-speed railway have developed remarkably in China.However,there exists a technology bottleneck in development of the ground on-board broadband wireless communication system.Beyond the basic speech communication,broadband wireless data transmission demands for passenger services are rising and a large amount of real-time on-board train operation information needs to be transmitted to the ground monitor & control center.Therefore,it is essential to build the cut-in broadband wireless system adaptable to h... |
