Abstract

In this study, we present a method for over-The-Air evaluation in which a full-rank channel matrix is created for a large-scale multiple-input multiple-output (MIMO) antenna in a cluster propagation environment with a Gaussian distributed incoming wave. In the proposed method, to mimic a fading emulator with a large number of scatterers, a limited number of scatterers are virtually arranged depending on the measured channel response. The analytical results show that even though the channel model comprised a limited number of scatterers, a full-rank channel matrix for a massive MIMO antenna system can be obtained by implementing the proposed method.
