摘要 高速铁路的建设离不开无线通信系统的支撑,而无线通信网络的设计则需立足于对典型环境下无线信道的深入研究.物理无线信道作为通信发生的媒介,其特性极大地影响着无线通信系统的性能.在高速铁路无线通信系统的设计中,需要用信道模型对复杂的传播信道加以描述.本文围绕高速铁路场景下的无线信道开展研究,探讨了高速移动复杂场景信道测量理论,并基于测试数据研究了信道的特征,同时,提出了高速移动复杂场景下的信道建模理论与面向工程设计的信道模型,为高速铁路无线通信系统的设计提供了电波传播预测工具,弥补了此类复杂场景下信道建模的研究不足,丰富了相关场景下的信道建模理论. The development of high-speed railway(HSR)relies on wireless communications,and the design of wireless network requires a deep investigation of wireless channels in typical environments.As the physical wireless channel is the medium over which communication happens,its properties significantly affect the performance of wireless communication system.In the design of HSR wireless communication system,channel models are required to describe the complex propagation channels.In this paper,we investigate measurement methods in HSR scenarios and characterize wireless channel based on measurements.We propose modeling method for HSR scenarios and many channel models for system design.We investigate the wireless channels in HSR environments,support propagation prediction tools for the system designs of HSR communications,compensate the deficiency of channel modeling in the complex scenarios,and enrich the theory of modeling in such scenarios.
