摘　　要：归纳了国内外已开展的高速铁路无线信道测量活动,总结了国际标准化组织关于高速铁路无线信道的相关提案和标准化模型,分类讨论了高速铁路在不同条件下无线信道大尺度、小尺度等方面的衰落特性,得出高速铁路无线信道特征参数受传播环境、位置等因素影响较大;根据高速铁路无线信道实际测量的问题,详细分析了基于理论方法的高速铁路无线信道建模类型,最后提出了未来的研究方向和重点。The conducted measurement campaigns, domestic and overseas, were presented. Meanwhile, proposals and standard channel models from the international standardization organization were reviewed. The large-scale and small-scale fading characteristics of High-Speed Railway wireless channels were adequately compared, and it is found that the channel parameters depend on the propagation environment and the distance between the transmitter and receiver. Moreover, due to difficulties encountered in realistic channel measurements, theoretical channel characterization methods were analyzed. Finally, open research issues were presented.
