A simulation model for wideband MIMO vehicle-to-vehicle fading channels in T-junction propagation environments

In this paper, we propose a high-performance simulation model for wideband multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) fading channels in T-junction propagation environments. The so-called Riemann sum method (RSM) is applied for the parametrisation of the simulation model. Furthermore, the statistical properties of the wideband MIMO V2V channel simulation model, such as the space-time-frequency cross-correlation function (STF-CCF), the two-dimensional spatial cross-correlation function (2D spatial CCF) and the temporal auto-correlation function (ACF) are studied. Finally, the high accuracy of the proposed simulation model is demonstrated by comparing the correlation properties of the simulation model with those of the underlying reference model. This research work is important for designers of MIMO V2V communication systems as the proposed simulation tool allows the analysis, optimization, and test of high data rate transmission schemes under realistic T-junction scattering conditions.
