Abstract：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 envi-ronments.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 sce-narios 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 communica-tions,compensate the deficiency of channel modeling in the complex scenarios,and enrich the theory of modeling in such scenarios.
