A Three Dimensional Parametric Model for Wideband MIMO Mobile-to-Mobile Channels

A three-dimensional (3-D) geometrical propagation model for wideband multiple-input multiple-output (MIMO) mobile-to-mobile (M-to-M) communications is proposed. Based on the geometrical model, a 3-D parametric reference model for wideband MIMO M-to-M multipath fading channels is developed. From the reference model, the space-time-frequency correlation function and the space-Doppler power spectral density are derived for a 3-D non-isotropic scattering environment. Finally, some simulation results are presented and compared with measured data. The close agreement between the theoretical and empirical curves confirms the utility of the proposed wideband model.
