Measurement-based simulation of mobile radio channels with multiple antennas using a directional parametric data model

Abstract

A parametric modeling approach for multiple input multiple output (MIMO) radio channels is introduced that is based on measured data. The MIMO measurement principle can be effectively exploited to estimate the propagation direction of any significant path at both ends of the wireless link simultaneously. From the estimated parameter sets a precise reconstruction of the multidimensional wave field in the aperture domains of time, frequency and space is possible. This enables various analyses and simulations of MIMO transmission links in a very realistic way.
