Performance of Uniform Concentric Circular Arrays in a Three-Dimensional Spatial Fading Channel Model
In this paper, the performance of uniform concentric circular arrays (UCCA) for multiple-input multiple-output (MIMO) receiver in a three-dimensional (3D) multi-path channel is investigated. Firstly, the analytical expressions for antenna spatial fading correlation and electromagnetic vector sensor (EVS) at each element are derived, where the UCCA configuration for MIMO receiver is considered. Then the effect of the angular parameters associated with the mean azimuth of arrival, azimuth spread, mean elevation of arrival, and elevation spread on the system performance is presented. The numerical and simulation results indicate that the excellent performance of the proposed UCCA MIMO antenna array system. In addition, comparisons between our theoretical results of the UCCAEVS antenna array with previous ULA and UCA antenna array show that the analysis is accurate and applicable to depict the 3D spatial fading channel model.
