Abstract:
Abstract—This paper proposes a three-dimensional (3D)
geometry based spatial correlation model for multiple-input
multiple-output (MIMO) communication environments. In the
proposed model, it is assumed that scatterers are distributed
about the receiver within a spheroid, while the transmitter and
receiver antennas are located at the focal points. Approximate
closed-form expressions are obtained for the normalized spatial
correlation coefficients of frequency non-selective Rician fading
channels. As a special case, the normalized spatial functions
are derived for Gaussian scatterer distribution. The closedform
expressions developed are verified by the simulation results
obtained using the WINNER Phase II channel model (WIM2)
[17]. Furthermore, the capacity performance of MIMO channels
is investigated using the proposed geometry based correlation
model.
