On the convergence of massive MIMO systems [PDF]
2014 IEEE International Conference on Communications (ICC), 2014 In this paper we examine convergence properties of massive MIMO systems with the aim of determining the number of antennas required for massive MIMO gains. We consider three characteristics of a channel matrix and study their asymptotic behaviour. Furthermore, we derive ZF SNR and MF SINR for a scenario of unequal receive powers.

Resource allocation in MIMO systems specific to radio communication [PDF]
Archives of Electrical Engineering, 2019 The performance of the multi-input multi-output (MIMO) systems can be improved by spatial modulation. By using spatial modulation, the transmitter can select the best transmit antenna based on the channel variations using channel state information (CSI).

On the degree of MIMO systems [PDF]
2007 IEEE International Symposium on Circuits and Systems (ISCAS), 2007 MIMO channels and wireless communications systems have generated a great deal of renewed interest in linear system theory. This paper presents two results. The first is a simple proof based on first principles, of the known fact that the McMillan degree of a causal M times M MIMO system is at least as large as the degree of its determinant.
