Abstract

Abstract

Two typical Vehicle-To-Vehicle (V2V) propagation channel models are proposed for the first time. One is that the channel is composed by Single-Bounce Transmit (SBT) and Single-Bounce Receive (SBR)components. The other is that the channel is composed by Double-Bounce (DB) components. Based on the two models, another model consisting of SBT, SBR, DB, and LOS components is proposed. It is assumed that the local scatterers move with random velocities in random directions and the velocity distributions of the moving scatterers with low and high speed are assumed to follow exponential and Gaussian Mixture (GM) distributions, respectively. The complex channel gains of the proposed V2V channel models are proposed, and the corresponding AutoCorrelation Function (ACF) and Doppler Power Spectral Density (PSD) are derived. The theoretical results are also compared with the available PSDs by measurements and good agreements are found between them.
