论文摘要
使用基于几何的无线电通道模型对车辆无线通道进行仿真，当散射器的数量显着较高时，在计算上是计算密集型的。在本文中，我们提出了一个新的基于几何的随机通道模型，以基于根据ambit过程理论开发的框架来模拟和分析上述通道。在合理的假设下，所提出的通道模型的基本数学结构还可以在淡出的统计数据，时空通道相关和多普勒频谱方面表征高迁移率通道的表征，除了确保可拖动的分析外。开发的算法有助于快速模拟高移动性通道，并说明了车辆通道的关键特征，包括外观和多path组件的外观和消失，空间一致性，并捕获了时间不断变化的延迟和与多路径组件相关的时间不变的延迟和多普勒之间的相关性。最后，我们进行模拟以获得有关基于提议的通道模型的典型车辆到基础结构通道特征的关键见解。
The simulation of vehicular wireless channels using geometry-based radio channel models is computationally intensive when the number of scatterers is significantly high. In this paper, we propose a new geometry-based stochastic channel model to simulate and analyze the aforementioned channels based on a framework developed from the theory of ambit processes. Under reasonable assumptions, the underlying mathematical structure of the proposed channel model enables the characterization of high mobility channels in terms of fading statistics, spatio-temporal channel correlation, and Doppler spectrum, besides ensuring tractable analysis. The developed algorithm facilitates fast simulation of high mobility channels and accounts for key features of vehicular channels including appearance and disappearance of multi-path components, spatial consistency, and captures the correlation between time-evolving delay and Doppler associated with multi-path components. Finally, we carry out simulations to obtain crucial insights about the characteristics of typical vehicle-to-infrastructure channels based on the proposed channel model.
