[Abstract]:Based on the spatial statistical channel in 3D environment, a VMF distribution model for MIMO antenna array is proposed. The topological structure of MIMO multi-antenna ULA,UYA and UCA in mobile station and base station is studied. The expression of ULA,UYA and UCA's spatial fading correlation (SFC) function under VMF (Von Mises Fisher) distribution model is obtained, and the sensitivity of different antenna array to average elevation (MEOA) is compared. It is shown that the SFC of the antenna array is determined by the centralized parameters, the average azimuth (MAOA) and the average elevation angle (MEOA). The channel performance of the model is in agreement with the theory.
