摘要
信道建模是设计无线通信系统的基础,为设计智慧交通系统,必须对车联网(vehicle to everything,V2X)信道进行深入研究.文中首先总结了V2X标准化信道的特点,讨论了天线设置、非平稳特性以及毫米波对V2X信道的影响;然后对车与车(vehicle to vehicle,V2V)信道参数进行了描述,并分析了V2V信道三种建模方式的优缺点;最后提出将来需要做的工作.
Channel modeling is the basis for the design of wireless communication systems.In order to design intelligence transportation systems,it is necessary to conduct in-depth research on the internet of vehicles channels.First,we summarize the characteristics of the vehicle to everything(V2X)standardized channels.Second,we discuss the influence of antenna settings,non-stationary characteristics and mm-wave on the vehicle to vehicle(V2V)channels.Third,we describe the V2V channel parameters and analyze the advantages and disadvantages of 3 modeling methods of it.Finally,we propose the work to be done in the future.
