摘要： 为建立更高效的智能车对车(Vehicle To Vehicle,V2V)通信系统,针对密集隧道空间多入多出系统(Multiple Input Multiple Output,MIMO)移动传播环境,提出新型三维(Three Dimensional,3D)车载多散射通信信道模型.分析波达信号水平面和仰角平面发射角(Angle Of Departure,AOD)和到达角(Angle Of Arrival,AOA)概率密度分布函数(Probability Density Function,PDF).与以往模型及测量对比,提出模型符合真实隧道环境中无线信道特性,拓展了V2V通信技术的研究.

关键词: V2V移动通信, 隧道空间信道模型, 发射角, 到达角, 概率密度函数

Abstract: A three dimensional (3D) modified tunnel multi-bounced scattering channel model for vehicle to vehicle mobile communication is proposed under the assumption of equivalent scattering point. In this model, multi-antenna technology is adapted in both the mobile transmitter and receiver and there are line of sight (LOS) and non-LOS (NLOS) propagation paths between the transmitter and receiver. Analytical expressions of the probability density function (PDF) of the angle-of-departure (AOD) and angle-of-arrival (AOA) are presented according to the 3D MIMO channel model. Results show good agreement with the existing V2V scattering channel models and measured data in real tunnel environment,demonstrating the rationality of the underlying channel model.

Key words: V2V mobile communication, tunnel spatial channel model, angle of departure, angle of arrival, probability density function
