摘要:

车辆排队被认为是车辆对车辆(V2 V)通信的关键用例之一。然而,它的好处只能通过高度可靠的无线传输来实现。由于用于V2 V的5.9GHz频带遭受高拥塞,在本文中,我们考虑使用地面电视频率进行排内通信。为了能够充分评估新频段的潜力,需要在这些频率下建立V2 V通信的传播模型。因此,本文报告了新的V2 V传播测量及其建模结果。特别是,我们提出了一个双斜率双阴影模型作为最准确的一个,基于使用贝叶斯信息准则的各种模型的比较。我们还研究了阴影的时空自相关特性,这原来是依赖于车辆的速度。所提出的路径损耗和阴影模型不同于为5.9GHz频带提出的路径损耗和阴影模型。大多数情况下,在电视波段的青睐,如所示,例如,在统计学上没有显著的影响。

英文摘要:

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.
