Hybrid-Field Channel Estimation for XL-MIMO Systems: Dictionary-based Sparse Signal Recovery
David William Marques Guerra, Taufik Abrao
Extremely large-scale multiple-input multiple-output (XL-MIMO) systems are a key technology for future wireless networks, but the large array aperture naturally creates a hybrid-fi…
Dual-Function Beam Pattern Design for Multi-Target ISAC Systems: A Decoupled Approach
Wilson de Souza Junior, Taufik Abrao, Amine Mezghani +1
We investigate the beampattern design problem for mono-static multi-user (MU) multi-point-target integrated sensing and communication (ISAC) systems, where a dual-function multiple…
Beamforming Control in RIS-Aided Wireless Communications: A Predictive Physics-Based Approach
Luis C. Mathias, Atefeh Termehchi, Taufik Abrão +1
Integrating reconfigurable intelligent surfaces (RIS) into wireless communication systems is a promising approach for enhancing coverage and data rates by intelligently redirecting…
Manifolds in Power Systems Optimization
Lucca Rodrigues Pinto, Wilson de Souza Junior, Jaime Laelson Jacob +2
Manifold optimization (MO) is a powerful mathematical framework that can be applied to solving complex optimization problems with objective functions (OFs) and constraints on compl…
