In this paper, we propose a new geometrical two-erose-ring scattering model for the multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) fading channels. In this model, the line-of-sight (LOS) and non-line-of-sight (NLOS) components are all considered. Based on the geometrical model, a reference model and the corresponding simulation model are derived. Their statistical properties such as the three-dimensional (3D) space-time cross-correlation function (CCF), the two-dimensional (2D) spatial cross-correlation function (2D spatial CCF), and the temporal autocorrelation function (ACF) are studied. For computing the parameters of the simulation model, the extended method of exact Doppler spread (MEDS) are used. The close agreement between the statistical properties of the simulation model and those of the reference model are demonstrated. We believe that this research work is important for designers to develop, analysis, test, and optimization the future MIMO M2M communication systems.
