Analysis of the influence of wireless channel environment on LTE-V2X communication performance

摘要

As the LTE-V2X function of intelligent connected vehicle plays an important role in safety warning and automatic driving, how to quantitatively and accurately evaluate the wireless communication capabilities of vehicle is the focus of intelligent connected vehicle's evaluation. The vehicle communication capability is not only restricted by its own chip capability and antenna system gain, but also affected by the external wireless channel environment. Aiming at the communication interruption problem found in the actual road test of the LTE-V2X function in the early stage, this paper selects three typical road scenarios to collect and analyze data such as the communication distance and packet error rate. Next, channel modeling and laboratory reproduction of the collected wireless channel environment will be implemented, which is the basis of the reliable communication of intelligent connected vehicle.
