在过去的几年里，发光二极管（LED）由于其使用寿命长，抗振动性高，以及由于其上升时间短而具有更好的安全性能，在汽车照明中变得非常普遍。许多现有的工作使用已经存在于车辆中的LED，诸如刹车灯、转向信号灯和前照灯，以利用可见光通信（VLC）来执行车辆到车辆（V2V）通信。尽管如此，很少有研究得出的VLC与经验数据从真实的世界或现实的假设分析模型。此外，实验工作通常是在封闭的环境中进行的，照明系统是专门定制的，而不是现实生活中的照明系统。在本文中，我们进行了分析研究，试图在一个现实的V2V设置中推导VLC通道模型。该模型与未经修改的现成的踏板车尾灯获得的真实世界的数据进行评估，结果表明，该模型能够准确地估计接收功率的踏板车尾灯的距离可达10米。此外，本文还讨论了几个准则建模VLC辐射行为时，使用不同类型的LED尾灯。
Over the past few years, Light Emitting Diode (LED) has become very common in automotive lighting due to its long service life, high resistance to vibration, and better safety performance due to its short rise time. A number of existing works use LEDs that already exist in vehicles, such as brake lights, turn signals, and headlamps, to carry out vehicle-to-vehicle (V2V) communications with visible light communications (VLC). Nonetheless, very few studies derive analytical models for VLC with empirical data obtained from the real world or with realistic assumptions. In addition, experimental works were often conducted in closed environments with lighting systems that are specifically customized, instead of real-life lighting systems. In this paper, we perform an analytical study that attempts to derive VLC channel models in a realistic V2V setting. The proposed model is evaluated against the real-world data obtained with unmodified off-the-shelf scooter taillights, and the results show that the proposed model is able to accurately estimate the received power of the scooter taillight at distances of up to 10 meters. In addition, this paper also discusses several guidelines for modeling VLC radiation behaviors when different types of LED taillights are used.
