Space-Time-Delay Correlation of 3-D MIMO Channel Model

In this paper, we present a 3-D MIMO channel model for wideband communication based on the geometric scattering channel model. The space-time-delay correlation is also derived and presented in the case of non-isotropic scattering distribution. We are interested in two MIMO array systems: uni-polarized antenna array and bi-polarized antenna array. For the bi-polarized MIMO systems, the polarizations of all the used antennas are imperfectly orthogonal. Thus the correlation between antennas can be occurred.
