论文摘要
在本文中，提出了针对非平稳车辆到车辆（V2V）多输入多输出（MIMO）通道的实用模型。新模型考虑了多普勒频率的更准确的输出阶段，并通过Taylor系列的扩展简化了。它也适用于以任意速度和移动发射器（MT）和移动接收器（MR）的任意速度和轨迹生成V2V通道系数。同时，研究和分析了路径延迟和功率的通道参数。统计特性的闭合形式表达式，即时间自相关函数（TACF）和空间互相关函数（SCCF），也以遵守VON MISES（VM）分布的到达角度（AOA）和出发角度（AOA）和出发角度（AOD）（AOD）得出。另外，理论，模拟和测量结果之间的良好协议验证了所提出模型的正确性和实用性。
In this paper, a practical model for non-stationary Vehicle-to-Vehicle (V2V) multiple-input multiple-output (MIMO) channels is proposed. The new model considers more accurate output phase of Doppler frequency and is simplified by the Taylor series expansions. It is also suitable for generating the V2V channel coefficient with arbitrary velocities and trajectories of the mobile transmitter (MT) and mobile receiver (MR). Meanwhile, the channel parameters of path delay and power are investigated and analyzed. The closed-form expressions of statistical properties, i.e., temporal autocorrelation function (TACF) and spatial cross-correlation function (SCCF) are also derived with the angle of arrival (AoA) and angle of departure (AoD) obeying the Von Mises (VM) distribution. In addition, the good agreements between the theoretical, simulated and measured results validate the correctness and usefulness of the proposed model.
