在本文中，我们提出了一种基于几何的多输入多输出（MIMO）车辆到车辆（V2 V）通信在实际隧道场景中的信道模型。在所提出的信道模型中，从发射机发送的波在到达接收机之前经历视距（LoS）和非视距（NLoS）。推导了传播路径和传播角度的时变参数，以表征信道的非平稳性。此外，我们推导出所提出的V2 V信道模型的相关特性函数，它们是空间互相关函数（CCF），时间自相关函数（ACF），频率CCF，以及多普勒功率谱分布（PSD）。研究和讨论了隧道不同物理特性的传播特性以及发射器和接收器的不同运动特性的大量仿真结果;它们表明所提出的信道模型适合描述实际的V2 V隧道通信场景。
In this paper, we propose a geometry-based channel model for multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) communications in practical tunnel scenarios. In the proposed channel model, the waves transmitted from the transmitter experience line-of-sight (LoS) and non-LoS (NLoS) before arriving at the receiver. The time-varying parameters of the propagation paths and angles are derived to characterize the channel non-stationarity. Furthermore, we derive the correlation property functions of the proposed V2V channel model; they are space cross-correlation functions (CCFs), temporal auto-correlation functions (ACFs), frequency CCFs, as well as the Doppler power spectrum distributions (PSDs). Numerous simulation results of the propagation characteristic for different physical properties of the tunnel, as well as the different motion properties of the transmitter and receiver, are studied and discussed; they demonstrate that the proposed channel model is suitable for describing the practical V2V tunnel communication scenarios.
