    A 3D Geometry-based spatial correlation model for mimo channels
    Tennakoon, P; Wavegedara2, CB
    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.
