A Novel Geometrical Mixed-bounce Two-ring Simulation Model for MIMO Mobile-to-mobile Isotropic Communication Channels

摘要

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 simulation model for mobile-to-mobile channel under the assumption of fiat fading. With further assumption of isotropic scattering, the expression for two dimensional (2-D) Space Time Cross-correlation (STCC) function between any two sub channels are derived. Comparing the statistical properties of the deterministic simulation model with the reference model indicates a 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.
