Performance Analysis of a Massive MIMO System in Indoor Scenario
Massive multiple-input multiple-output(MIMO)is a potential candidate key technology for the fifth generation of wireless communication systems.In research to date,many investigations are based on theoretical channels with independent and identically distributed(i.i.d.)Rayleigh channels.In this paper,we focus on how a massive MIMO system performs in real propagation environments,specifically on channel performance of a realistic indoor scenario using large linear and circular antenna arrays.With massive MIMO,as the number of antennas increases and becomes much larger than the number of users,we get smaller singular value spreads and better orthogonality between user channels,whats more,the singular value spreads become more stable over channel realizations.The stability of singular value spread implies that bad channel conditions can be largely avoided.By analyzing the singular value spread of a massive MIMO system,it shows the measured channel can achieve performance close to the i.i.d.Rayleigh channel.So it can be conclude that the theoretical advantages of massive MIMO can also be harvest in real channel.
