Abstract	Long Term Evolution (LTE) is commonly deemed to be a promising system for the future High-Speed Railway (HSR). The object of this paper is modeling of the broadband multipleinput multiple-output (MIMO) train-ground channel in LTE system based on the measurements on HSR viaducts. A couple of measurement campaigns are conducted along the Harbin-Dalian passenger dedicated line. The statistical distributions of some critical large and small scale parameters are firstly presented including delay spread, angle spread at transceivers and K factor. Then the channel model is proposed following a geometry-based stochastic modeling approach and the channel transfer matrix is derived to depict the time-varying environment.In particular, the spatial cross-correlation function (CCF) between subchannels,power delay profile (PDP) and the Doppler spectrum are simulated and analyzed to validate the practicality of our model. All these results significantly promote the evaluation and development of the HSR communication system based on LTE.
