A non-stationary geometry-based scattering model for street vehicle-to-vehicle wideband MIMO channels

摘要

In this paper, a non-stationary geometry-based scattering model for street wideband multi-input multi-output (MIMO) vehicle-to-vehicle (V2V) fading channel is proposed. It is assumed that the static scatterers on the both roadside are uniformly distributed on time-varying ellipses, and the mobile scatterers are uniformly distributed in time-varying segment of the road. To avoid complicated procedure in deriving the analytical expressions of the channel parameters and functions, the channel is realized first, then the time-varying channel properties and parameters are investigated. In this work, we extend the proposed narrowband model to wideband and also introduce the carrrier frequency and bandwidth into the model.
