C-V2X技术现状与性能对比

V2X作为智能网联汽车的关键技术,可实现车与车(V2V)、车与基础设施(V2I)、车与行人(V2P)、车与网络(V2N)等互联,将车辆信息与外界信息共享,增强车辆智能感知能力。本文从通信架构、标准进展、技术参数等方面研究分析了V2X两种主流技术的不同,并结合仿真情况,给出了两种技术的理论性能仿真结果。

C-V2X technologies introduction and performance evaluation

V2X, as key technologies of intelligent and connected vehicle, can implement to support vehicle-to-vehicle(V2V),vehicle-to-infrastructure(V2I), vehicle-to-pedestrian(V2P), vehicle-to-network(V2N) scenarios. Furthermore, V2X can be deployed to enhance the ability of vehicle information collection. In this paper, two main V2X techniques, also known by DSRC and LTE-V, are introduced from network architecture, standard progress and technique designs. Finally, some simulation results are given based on several classical scenarios.
