自动驾驶汽车配备了多个高分辨率传感器和摄像头，以准确地查看周围环境。同样重要的是，它们将需要相互交换如此高的数据速率，以便更广泛地了解其环境。在车辆通信中使用高带宽毫米波（mmWave）谱带可以满足这种对高数据速率交换的需求。在尝试设计任何毫米波车载通信系统之前，需要完全理解这种毫米波移动的环境的传播特性。在本文中，我们利用WinProp软件套件中的光线跟踪功能，研究了车载通信中毫米波信道的传播特性。在此过程中，我们提出了车辆到基础设施（V2I）的通信方案在WinProp中的实现。通过仿真结果，我们能够表明，大约20 dB的信号强度下降可以在5秒内发生。
Autonomous vehicles are equipped with multiple high-resolution sensors and cameras for an accurate local view of their surroundings. Equally important, they will need to exchange such high data-rate among each other for a wider view of their environments. The use of high-bandwidth millimeter-wave (mmWave) spectrum bands in vehicular communications can satisfy such demand for high data-rate exchange. Before attempting to design any mmWave vehicular communication system, there is a need to fully understand the propagation characteristics of such mmWave mobile environment. In this paper, we leverage the ray tracing capabilities in the WinProp software suite and study the propagation characteristics of mmWave channels in vehicular communications. In doing so, we present the implementation of the Vehicle-to-Infrastructure (V2I) communication scenario in WinProp. Via simulation results, we are able to show that approximately 20 dB degradation of signal strength can happen within 5 seconds.
