车联网信道特性综述

Overview of the channel characteristics of V2X

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.

Abstract: 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.
