论文摘要
车辆排被认为是车辆到车辆（V2V）通信的关键用例之一。但是，只有通过高度可靠的无线传输才能实现其好处。由于用于V2V的5.9GHz频带遭受了高拥堵状的困扰，因此，我们考虑使用陆地电视频率用于平台内通信。为了能够充分评估新频段的潜力，需要在此类频率下进行V2V通信的传播模型。因此，本文报告了新的V2V传播测量及其建模结果。特别是，根据使用贝叶斯信息标准对各种模型进行比较，我们提出了最精确的双坡双阴影模型。我们还研究了阴影的时空自相关属性，事实证明这取决于车辆的速度。提出的路径损失和阴影模型与5.9GHz频段的提议不同。大多数情况下，有利于电视乐队，如，例如，阻止汽车没有统计学上的显着影响。
Vehicle platooning is considered as one of the key use cases for vehicle-to-vehicle (V2V) communications. However, its benefits can be realized only with highly reliable wireless transmission. As the 5.9GHz frequency band used for V2V suffers from high congestion, in this paper, we consider the use of the terrestrial TV frequencies for intra-platoon communications. In order to be able to evaluate the potential of the new bands fully, propagation models for V2V communications at such frequencies are needed. Therefore, this paper reports new V2V propagation measurements and their modeling results. Particularly, we propose a Double Slope Double Shadowing model as the most accurate one, based on a comparison of various models using the Bayesian Information Criteria. We also investigate the space-time autocorrelation properties of the shadowing, which turned out to be dependent on the speed of vehicles. The proposed path loss and shadowing model differs from the ones proposed for the 5.9GHz band. Mostly, in favor of the TV band, as shown by, e.g., no statistically significant impact of a blocking car.
