3D MIMO channel model based on field measurement campaign for UMa scenario

Abstract

This paper reports the methodology and results from our latest field measurement campaign for characterizing the 3-dimensional (3D) MIMO channel, particularly in the elevation domains, in a typical urban macro (UMa) environments in Beijing, China. Stochastic channel model parameters are obtained based on the high-resolution multi-path parameter estimates. In addition, a distance dependent elevation angular spread model is proposed based on field observations. These works enables the realistic evaluation of 3D MIMO system performance and extends the applicability of the ITU SCM models in 3D MIMO system study.
