论文摘要
近年来，可见光通信（VLC）技术的应用潜力作为射频（RF）技术的替代方案和补充，吸引了人们的注意力。基础VLC渠道的研究是设计VLC通信系统的基础。在本文中，为车辆VLC（VVLC）多输入多输出（MIMO）渠道提出了一种新的非平稳几何街角模型。提议的模型考虑了车速和方向的变化。散射器的类别包括固定的散射器和移动散射器（MS）。基于提出的模型，我们得出了通道脉冲响应（CIR）并探索VVLC通道的统计特征。研究了VVLC通道的通道增益和均方根（RMS）延迟扩散。此外，还研究了速度变化对模型统计特征的影响。拟议的渠道模型可以指导未来的车辆到基础设施（V2I）和车辆到车辆（V2V）光通信系统设计。
In recent years, the application potential of visible light communication (VLC) technology as an alternative and supplement to radio frequency (RF) technology has attracted people's attention. The study of the underlying VLC channel is the basis for designing the VLC communication system. In this paper, a new non-stationary geometric street corner model is proposed for vehicular VLC (VVLC) multiple-input multiple-output (MIMO) channel. The proposed model takes into account changes in vehicle speed and direction. The category of scatterers includes fixed scatterers and mobile scatterers (MS). Based on the proposed model, we derive the channel impulse response (CIR) and explore the statistical characteristics of the VVLC channel. The channel gain and root mean square (RMS) delay spread of the VVLC channel are studied. In addition, the influence of velocity change on the statistical characteristics of the model is also investigated. The proposed channel model can guide future vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) optical communication system design.
