Modeling and characteristics of mobile-to-mobile wideband MIMO channel based on the geometrical multi-radii two-rings with specified frequency selectivity

A wideband mobile-to-mobile multiple-input multiple-output channel model based on geometrical multi-radii two-rings is proposed for ease of measured or specified frequency selectivity implementation. Assuming double bounced scattering and two dimensional isotropic wide-sense stationary uncorrelated scattering, we show that how it can be applied to the proposed model by aid of a numerical optimization technique, and the performance is verified by the simulation result. To investigate the fading statistics of the proposed model, we analytically derive the temporal auto-correlation function, space-time correlation function, and frequency correlation function. We believe the proposed model is useful for flexible design for diverse specification and universal performance.
