Manifold-Based Optimizations for RIS-Aided Massive MIMO Systems
Wilson de Souza Junior, David William Marques Guerra, José Carlos Marinello +2
Manifold optimization (MO) is a powerful mathematical framework that can be applied to optimize functions over complex geometric structures, which is particularly useful in advance…
Energy-Efficient Active Element Selection in RIS-aided Massive MIMO Systems
Wilson Souza, José Carlos Marinello, Taufik Abrão
This chapter delves into the critical aspects of optimizing energy efficiency (EE) in active reconfigurable intelligent surface (RIS)-assisted massive MIMO (M-MIMO) wireless commun…
Assessing the Potential of Space-Time-Coding Metasurfaces for Sensing and Localization
Herman L. dos Santos, Martin Voigt Vejling, Taufik Abrão +1
Intelligent metasurfaces are one of the favorite technologies for integrating sixth-generation (6G) networks, especially the reconfigurable intelligent surface (RIS) that has been…
EMF Exposure Mitigation in RIS-Assisted Multi-Beam Communications
Herman L. dos Santos, Cristian J. Vaca-Rubio, Radosław Kotaba +3
This paper proposes a method for reducing {third-party} exposure to electromagnetic fields (EMF) by exploiting the capability of a reconfigurable intelligent surfaces' (RIS) to man…
Raptor-IRSA Grant-free Random Access Protocol for Smart Grids Applications
Angel Esteban Labrador Rivas, Taufik Abrão
This paper deals with the reliability of random access (RA) protocols for massive wireless smart grid communication (m-SGC). We propose and analyze an improved grant-free RA (GF-RA…
Machine Learning-based Methods for Joint {Detection-Channel Estimation} in OFDM Systems
Wilson de Souza Junior, Taufik Abrao
In this work, two machine learning (ML)-based structures for joint detection-channel estimation in OFDM systems are proposed and extensively characterized. Both ML architectures, n…
