Analysis of Wireless Channel Model Characteristics in the High-Speed Railway Scenarios

With the complexity of the surrounding environment of the high-speed railways(HSR) and the fast-moving of trains, the wireless channel propagation characteristics are quite different from ordinary channels. In this paper, firstly, the conventional channel modeling methods is introduced and highspeed railway common scenarios are classified. Then, the HSR wireless channel model in different scenarios is built based on the TDL model. Finally, the characteristics of channels based on the TDL model in different scenarios are analyzed and compared. The simulation results show that the TDL model can be well applied to channel modeling in high-speed railway scenarios.
