Massive MIMO-NOMA Networks with Imperfect SIC: Design and Fairness Enhancement
de Sena, Arthur S.; Nardelli, Pedro H. J.; Lima, F. Rafael M.; da Costa, Daniel B.; Ding, Zhiguo; Dias, Ugo S.; Papadias, Constantinos B. (IEEE, 11.06.2020)This paper addresses multi-user multi-cluster massive multiple-input-multiple-output (MIMO) systems with non-orthogonal multiple access (NOMA). Assuming the downlink mode, and taking into consideration the impact of imperfect ... -
Massive MIMO-NOMA Networks With Successive Sub-Array Activation
Sousa de Sena, Arthur; Nardelli, Pedro H. J.; da Costa, Daniel; Ding, Zhiguo; Dias, Ugo S.; Papadias, Constantinos B. (IEEE, 04.12.2019)In this paper, we propose a novel successive sub-array activation (SSAA) diversity scheme for a massive multiple-input multiple-output (MIMO) system in combination with non-orthogonal multiple access (NOMA). Considering a ... -
Successive Sub-Array Activation for Massive MIMO-NOMA Networks
Nardelli, Pedro H. J.; de Sena, Arthur S.; da Costa, Daniel B.; Ding, Zhiguo; Dias, Ugo S.; Papadias, Constantinos B. (IEEE, 27.07.2020)In this paper, we propose a novel successive sub-array activation (SSAA) diversity scheme for a massive multiple-input multiple-output (MIMO) system in combination with non-orthogonal multiple access (NOMA). A single-cell ... -
What Role Do Intelligent Reflecting Surfaces Play in Multi-Antenna Non-Orthogonal Multiple Access?
de Sena, Arthur S.; Carrillo, Dick; Fang, Fang; Nardelli, Pedro H. J.; da Costa, Daniel B.; Dias, Ugo S.; Ding, Zhiguo; Papadias, Constantinos B.; Saad, Walid (IEEE, 28.10.2020)Massive multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA) are two key techniques for enabling massive connectivity in future wireless networks. A massive MIMO-NOMA system can deliver remarkable ...
