摘　　要：随着车载网络的发展,新的无线电技术已经成为人们关注的焦点.车辆间通信既要求超可靠低时延,同时又对通信数据速率有较高的要求.本文针对韩国大田的城市环境进行仿真,并表征23GHz车载移动通信信道的特性.利用射线跟踪仿真萃取路径损耗、莱斯K因子、均方根时延扩展和角度扩展等典型信道参数,定量地分析并总结其对车辆通信的影响,为毫米波车载移动通信系统的部署提供参考和指导性建议.With the development of the vehicular network,new radio technologies have been in the spotlight.Communication between vehicles requires both ultra-reliability and low latency,and at the same time has high requirements for communication data rates.The urban scenario of Daejeon,South Korea,is simulated and the characteristics of the vehicular mobile communication channel at 23 GHz are characterized.Typical channel parameters such as path loss,Ricean K-factor,root mean square delay spread,and angle spread are extracted through ray tracing simulation.The influence of parameters on vehicle communication is quantitatively analyzed and summarized,providing reference and guidance suggestions for the design of millimeter wave vehicular mobile communication system.
