A novel geometrical mixed-bounce two-ring reference model for MIMO mobile-to-mobile communication channel

Abstract

An accurate modeling of multiple-input multiple-output (MIMO) channels is a prerequisite for designing multi-antenna system. In this paper, we propose a Geometrically Mixed-Bounce Two-Ring Reference Model for Mobile-to-Mobile channel under the assumption of flat fading. With further assumption of isotropic scattering, the expression for three dimensional (3-D) space-time cross-correlation (STCC) function between any two sub channels are derived. Comparing the statistical properties of the deterministic simulation model with this reference model indicates good agreement thus the importance of this model. The result obtained is in conformity with that of the double bounce and single bounce two ring models. © 2012 Binary Information Press.
