摘　　要：针对传统的高速列车实时通信难的问题,提出了一种适用于高速列车的动态建链通信模型。具体地,当列车进入基站通信范围内时,为便于与基站建立通信,基站端与列车端通过各自的旋转保障通信链路的连接,并通过计算确定列车端与基站各自的实时旋转角度。考虑不同的路径函数、基站高度、列车行驶速度,利用MATLAB对列车通信过程中的信号传递方向以及旋转角度进行仿真。仿真结果表明,该模型能实时模拟不同情况下列车端、基站的角度变化情况,为高速移动通信提供了新的方案。Aiming at the difficulty of real-time communication for traditional high-speed trains,a base station model of millimeter-wave communication for high-speed trains is proposed.Specifically,when the train enters the communication range of the base station,it establishes communication with the base station.The base station and the train ensure the connection of the communication link through their respective rotations,and determine the respective real-time rotation angles of the train and the base station through calculation.Considering different path functions,base station heights,and train speeds,this paper uses MATLAB to simulate the signal transmission direction and rotation angle during the train communication process.Simulation results indicate that the model can simulate angle changes of the train and the base station in real time under different conditions,which provides a new solution for high-speed mobile communication.
