【摘要】：该文首次提出两种典型的移动散射体存在的车辆对车辆(V2V)的无线传播信道模型,一种是基于一次散射发射(SBT)和一次散射接收(SBR)的信道,另一种是基于两次散射(DB)的信道,并在这两种模型的基础上给出了同时包含一次散射发射,一次散射接收,两次散射和视距(LOS)分量的信道模型。在假设移动散射体的运动速度和方向都随机且运动速度较小和较大的散射体速度分别用指数分布和混合高斯分布来描述的情况下,给出了这些传播信道的复增益,通过计算得到了信道的自相关函数(ACF)和多普勒功率谱密度(PSD)。文中还将理论计算得到的多普勒谱与已有文献的测量结果进行了对比,两者符合得较好。
[Abstract]:In this paper, for the first time, two kinds of wireless propagation channel models of vehicle to vehicle (V2V) with two typical moving scatters are proposed, one is based on single scattering emission (SBT) and the other is based on single scattering receiver (SBR), and the other is based on two-time scattering (DBB).On the basis of these two models, a channel model including one scattering emission, one scattering receiver, two scattering and one line-of-sight) component is given.Under the assumption that the moving velocity and direction of the moving scatterer are random, the smaller velocity and the larger velocity are described by exponential distribution and mixed Gao Si distribution respectively, the complex gain of these propagation channels is given.The channel autocorrelation function (ACF) and Doppler power spectral density (PSD) are calculated.The Doppler spectra obtained by theoretical calculation are compared with the measured results of previous literatures, and the results are in good agreement with each other.
