Massive MIMO Channel Models: A Survey

Abstract EN

The exponential traffic growth of wireless communicationnetworks gives rise to both the insufficient networkcapacity and excessive carbon emissions.

Massive multiple-input multiple-output (MIMO) can improve the spectrum efficiency(SE) together with the energy efficiency (EE) and has beenregarded as a promising technique for the next generationwireless communication networks.

Channel model reflects thepropagation characteristics of signals in radio environments andis very essential for evaluating the performances of wireless communicationsystems.

The purpose of this paper is to investigatethe state of the art in channel models of massive MIMO.

First,the antenna array configurations are presented and classified,which directly affect the channel models and system performance.

Then, measurement results are given in order to reflect themain properties of massive MIMO channels.

Based on theseproperties, the channel models of massive MIMO are studiedwith different antenna array configurations, which can be usedfor both theoretical analysis and practical evaluation.
