Accurate Closed-Form Approximations to Channel Distributions of RIS-Aided Wireless Systems
TL;DR: In this article, the authors proposed highly accurate closed-form approximations to channel distributions of two different reconfigurable intelligent surface (RIS)-based wireless system setups, namely, dual-hop RIS-aided (Ris-DH) scheme and RISaided transmit (rIS-T) scheme, for arbitrary number of reflecting metasurface elements.
Journal ArticleDOI
What Role Do Intelligent Reflecting Surfaces Play in Multi-Antenna Non-Orthogonal Multiple Access?
Arthur Sousa de Sena,Dick Carrillo,Fang Fang,Pedro H. J. Nardelli,Daniel Benevides da Costa,Ugo Silva Dias,Zhiguo Ding,Constantinos B. Papadias,Walid Saad +8 more
TL;DR: This article demonstrates the main roles of IRSs in MIMO-NOMA systems and identifies key challenges and performs a comprehensive discussion of the main performance gains that can be achieved in IRS-assisted massive MIMo-NomA (IRS- NOMA) networks.
