三维空间域VMF分布模型的多天线系统性能
Multi-antenna system performance of VMF distribution model based on three-dimensional space
摘要
Abstract
As for the mobile communication environment in the city,the von Mises Fisher (VMF) distribution model for a scatterer with anisotropic distribution was proposed.The concept of the scattering cluster was introduced into the mobile communication environment of outdoor macrocells.Based on the multiple-input and multiple-output (MIMO) uniform Y array (UYA) and the uniform circular array (UCA) topology,the VMF distribution model can estimate the important channel parameters of multipath fading channels,such as the spatial fading correlation function (SFC) of UYA and UCA,the channel capacity of the fading channel model,the sensitivity of the multi-antenna array of UYA and UCA to the mean colatitude of arrival and so on.The application of SFC in solving the channel covariance matrix is extended.The results show that the performance of the MIMO multi-antenna system depends on the antenna array element spacing and the angle of arrival.The parameter estimation results of the proposed model are suitable for the realistic city mobile communication environments.The study of SFC and the channel capacity of UYA and UCA expands the application of the VMF distribution model in three-dimensional space domain in the field of mobile communication,and provides a powerful tool for the evaluation of the channel parameters of the MIMO multi-antenna array and the simulation of wireless communication systems关键词
