摘　　要：我国高速铁路(简称"高铁")建设取得了举世瞩目的成就,高铁车地通信问题也成为学术界、产业界研究的热点,本文分析了高铁信道模型的特点,回顾了高铁信道测量和研究的已有成果,归纳了现阶段标准化组织高铁信道提案和模型,研究了高铁无线信道测量和建模的特殊问题,如不同覆盖方式信道模型的差异,小区重叠时无线信道特征,高铁信道互易性问题,非平稳相关散射特征,基于马尔科夫链生灭过程时变信道等问题。The high-speed railway in China attracts the world＇s attention.The wireless communication between the train and the ground has been one of the most top issues in industry and academe.The wireless is critical when designing channel communication system.In this paper,the related work on measurement and research,the recent proposals have been reviewed. Then the challenges of measurement and channel modeling in high speed scenario are presented such as the differences between various wireless coverage methods,the characteristics of wireless channel in overlapped cell field,channel reciprocity,non widesense stationary uncorrelated scattering（WSSUS）and birth-death propagation of multipath channel.
