A wideband MIMO vehicle-to-vehicle channel model in T-junction scattering environments

In this paper, we model a wideband multi-input multi-output (MIMO) channel model for vehicle-to-vehicle (V2V) communications in T-junction street scattering environments. The proposed channel model takes into account both single- and double-bounce rays, and the exact relationship between angle of arrival (AOA) and angle of departure (AOD). Based on this relationship, the stochastic and the deterministic simulation model are derived. Analytical solutions are provided for the space-time cross-correlation function (ST-CCF), the temporal auto-correlation function (ACF), and the 2D space cross-correlation function (CCF). Finally, simulation results show the excellent correspondence between the temporal and the space correlation properties of the channel simulator and the reference model. This research work can be used for the derivation of wideband V2V channel simulators. Furthermore, the proposed model lays a foundation for further studies of V2V communication systems.
