Statistical analysis of a mimo vehicle-to-vehicle channel model based on the geometrical scattering environments

A reference model for multiple-input multiple-output (MIMO) vehicle-to-vehicle (V2V) frequency nonselective channels based on the geometrical T-shaped scattering model is proposed. In this model, both single and double-bounce multipath components are taken into account. Then the corresponding deterministic simulation model is derived from the reference model. By using the Riemann sum method (RSM) and the exact relationship between the angle-of-departure (AOD) and the angle-of-arrival (AOA), the parameters of the simulation model are determined. Furthermore, the correlation properties of simulation model are analyzed, including the space-time-frequency cross-correlation function (STF-CCF), the 2D space cross-correlation function (CCF), the temporal autocorrelation function (ACF) and the frequency autocorrelation function (FCF). The results illustrate the excellent correspondence between the space and time domain properties of the simulation model and those of the reference model.
