Overview of the channel characteristics of V2X

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.
