Evaluation of beam forming and multi antenna techniques in non-stationary propagation scenarios with HW emulator

This paper discusses a three-dimensional (3D) non-stationary channel modelling for the evaluation of multi antenna techniques with a hardware (HW) fading emulator or a software (SW) simulator. The proposed geometric stochastic channel modelling (GSCM) principle supports single or multi link emulations with both measured or simulated antenna patterns and dynamically evolving propagation environments. The modelling principle considers, e.g., 3GPP SCM(E), WINNER II, IMT-Advanced and WINNER+ channel models. The novelty of the paper is in the creation of smoothly evolving propagation and antenna orientation parameters with a linear interpolation of the specified location snapshots. We measured a throughput in four different non-stationary channels but also did a throughput comparison in 2D and 3D urban micro channel models.
