摘要:

当散射体的数目显著较高时,使用基于几何的无线电信道模型的车辆无线信道的仿真是计算密集的。在本文中,我们提出了一个新的基于几何的随机信道模型来模拟和分析上述信道的基础上,从理论的界限过程的框架。在合理的假设下,所提出的信道模型的基本数学结构,使高移动性信道的衰落统计,时空信道相关性和多普勒频谱方面的表征,除了确保易于处理的分析。所开发的算法有利于快速模拟高流动性的信道和帐户的车辆信道的关键功能,包括多径分量的出现和消失,空间一致性,并捕捉时间演变的延迟和多普勒与多径分量之间的相关性。最后,我们进行了模拟,以获得关键的见解典型的车辆到基础设施的通道的特征的基础上提出的通道模型。

英文摘要:

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.
