Abstract
In this paper, we first implement a full space MIMO simulation channel model based on the previous contributions in the methodology of extending the 2D geometry-based stochastic channel model (GSCM) to 3D conditions. Dual polarized anten-nas with a directional field pattern are considered, which are more general than the single polarization and omnidirectional pattern. We then derive the closed-form formula for channel correlation coefficients based on the GSCM methodology. We have also assessed the capacity performance and found that though the ergodic capacity can be significantly improved by considering the 3D scattering, the effectiveness largely depends on the degree of elevation angle spread. Lastly, we evaluate the validation of Kronecker model in capacity performance aspect and find it a promising candidate to enable explicit system analysis/design and to reduce the time consumption of system level simulation.
