Measuring cooperative massive MIMO in reverberation chamber

Abstract

Cooperative or distributed multiple-input multiple-output (MIMO) systems are promising techniques for achieving large performance gains in wireless networks. Recently, a novel method for measuring these systems on a reverberation chamber has been proposed. In this letter, this technique is used to measure different cooperative massive MIMO (CM-MIMO) systems. The correlations of these systems have been shown, and capacities under different conditions are provided for different CM-MIMO systems. In addition, the behavior of these systems with Rician fading is also analyzed. These results show the impact of these new propagations channels on the fifth-generation mobile communication systems, which will be basic for the development of such systems.
