摘要
毫米波通信能够满足目前车辆与基础设施之间通信中低延迟、高可靠性和高数据传输速率的要求,是V2I中的关键技术和重要研究方向。为探究中继车及车流量的不同对V2I通信的干扰,对毫米波(22.1~23.1 GHz)波段的高速场景中V2I通信进行了射线追踪仿真。考虑到频率规划策略、中继车数量和车流量的不同,分析比较了不同部署方式下的信干噪比分布,为V2I通信系统的设计和部署提供支持。
Millimeter wave communication can meet the requirements of low delay,high reliability and high data transmission rate in Vehicle-to-Infrastructure communication.It is a key technology and important research direction in V2I.In order to explore the interference of relay vehicles and different traffic flows on V2I communication,ray tracing simulations are performed on V2I communication in high-speed scenario in the millimeter wave(22.1~23.1 GHz)band.Considering the different frequency planning strategies,the number of relay vehicles and traffic flows,it analyzes and compares the SINR distribution under different deployments,so as to provide support for the design and deployment of V2I communication system.
