A Non-Stationary Geometry-Based Street Scattering Model for Vehicle-to-Vehicle Wideband MIMO Channels

Abstract

In this paper, a non-stationary geometry-based street scattering model for wideband multi-input multi-output vehicle-to-vehicle fading channels is proposed. It is assumed that the static scatterers on the both roadsides are uniformly distributed on time-varying ellipses, and the mobile scatterers are uniformly distributed in time-varying segments of the road. Both the relatively low- and high- speed mobile scatterers are under consideration, and the velocity distributions of the low- and high- speed moving scatterers are assumed to follow exponential and mixed Gaussian, respectively. In this work, we extend the proposed narrowband model to wideband and also introduce the carrier frequency and bandwidth into the model. In order to avoid complicated procedure in deriving the analytical expressions of the channel parameters and functions, the channel is realized first, then the channel properties and parameters are investigated.
