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).

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

3-D Geometrical Model for Multi-Polarized MIMO Systems
IEEE Access, 2017 Multiple-input multiple-output (MIMO) systems capacity is highly influenced by the correlation between antennas, and the high correlation will result in a low capacity.
