Abstract

This paper focuses on the modeling of High-Speed Railway (HSR) multiple-input multiple-output (MIMO) systems. By using the geometry-based statistical method and ray tracing technique, a train-ground channel model based on the measurement of actual channel is proposed. Then the time-domain attenuation, channel capacity, Doppler power spectrum are simulated and analyzed to verify the validity of our model. In addition, as the velocity of the HSR leads to critical time-selective fading, so the speed on the influence of these parameters are also analyzed in this paper. All these results significantly promote the evaluation, simulation and design of the wireless communication system based on long term evolution (LTE) application to the future high speed railway.
