高速铁路环境下的MIMO信道建模及仿真

MIMO channel modeling and simulation under the environment of high-speed railway

根据高速铁路环境下电波传播特性,基于多入多出(MIMO)无线散射信道模型,提出一种高速铁路无线环境下的MIMO无线信道模型,详细分析了其构建过程,并通过仿真得出MIMO信道的空域相关性随天线单元间距的增大而减小,拓展了MIMO信道衰落模型的研究。

This paper proposes an MIMO channel model under the environment of high-speed railway, based on the radio propagation around high-speed railway and the MIMO scattering wireless channel model, then emphasizes the construction of the modeling. The simulation results show that the spatial correlation consistently decrease with the increasing antenna spacing, which extends the research field of the MIMO channel modeling.
