摘要

本文提出一种新型的三维空间非平稳车载几何信道模型.我们采用圆柱体描述发射端（Mobile Transmitter，MT）以及接收端（Mobile receiver，MR）附近运动的车辆，而采用椭圆柱描述路边静止的建筑物.由于发射端和接收端的相对运动而使得本文提出的模型呈现时变非平稳几何特性.针对提出的三维空间信道模型，作者深入研究其统计特性，比如时域相关特性以及多普勒功率谱分布.仿真结果和过去研究结果进行比较，进而验证本文提出的信道模型能够很好地描述车载无线通信环境.

Abstract

This paper presents a novel three-dimension (3D) non-wide-sense stationary (non-WSS) geometry-based channel model for vehicle-to-vehicle (V2V) communication environments.We introduce the two-cylinder model to describe the moving vehicles and elliptic-cylinder models to depict the stationary roadside scenarios.The relative movement between the mobile transmitter (MT) and mobile receiver (MR) results in the time-varying geometric statistics that make our channel model non-stationary.Furthermore

the proposed channel statistics

i.e.

the time-varying space correlation functions (CFs) and Doppler power spectral density (PSD) are studied for different relative moving time instants.The results show that the proposed 3D non-WSS channel model is practical for characterizing real V2V channels.
