最近，研究界已经对毫米波（mmWave）频率用于车对车（V2 V）通信的可行性进行了积极的讨论。我们有助于这一讨论，通过提供明确的三维射线追踪模拟和现场试验测量39 GHz的频率之间的比较。V2 V通信的三个基本的实际和相关的情况下被认为涵盖了日常生活交通的几个重要场景。通过显式光线跟踪模拟，发现测量结果和模拟结果之间的密切匹配，从而验证了模拟模型和基本假设的可行性。此外，这些结果还揭示了使用毫米波频率进行V2 V通信的潜力和挑战。所获得的结果表明，参考信号接收功率（RSRP）水平是足够的噪声水平以上，甚至高达100米的TX和RX之间的距离的情况下，一个单一的阻碍汽车。结果还揭示了运动车辆在道路交叉口处与TX和RX车辆之间的LOS相交的影响，并且它们表明在短TX-RX间隔的情况下显著的阻塞损失。
Recently, an active discussion on the feasibility of Millimeter Wave (mmWave) frequencies for the Vehicle-to-Vehicle (V2V) communication have been carried out in research community. We contribute to this discussion by providing a comparison between explicit three-dimensional ray-tracing simulations and field trial measurements on 39 GHz frequency. Three basic practical and relevant cases for V2V communications are considered covering several important scenarios of daily life traffic. A close match between the measured and simulated results is found through explicit ray tracing simulations; thus validating the feasibility of the simulation model and underlying assumptions. Moreover, these outcomes also shed light on the potential and challenges of using mmWave frequencies for V2V communication. The acquired results indicate that the Reference Signal Received Power (RSRP) levels are sufficiently above the noise level even up to 100 m distance between TX and RX in case of a single obstructing car. Results also reveal the impact of moving vehicle intersecting the LOS between the TX and RX vehicle at road intersection, and they indicate a notable blockage loss in case of short TX-RX separation.
