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…
Reconfigurable Intelligent Surfaces-Enabled Intra-Cell Pilot Reuse in Massive MIMO Systems
Jose Carlos Marinello Filho, Taufik Abrao, Ekram Hossain +1
Channel state information (CSI) estimation is a critical issue in the design of modern massive multiple-input multiple-output (mMIMO) networks. With the increasing number of users,…
Improving Spectral Efficiency via Pilot Assignment and Subarray Selection Under Realistic XL-MIMO Channels
Gabriel Avanzi Ubiali, Taufik Abrao, Jose Carlos Marinello
The main requirements for 5G and beyond connectivity include a uniform high quality of service, which can be attained in crowded scenarios by extra-large MIMO (XL-MIMO) systems. An…
LSTM-ACB-Based Random Access for Mixed Traffic IoT Networks
Herman L. dos Santos, João H. I. Souza, José Carlos Marinello +1
We propose a novel random access (RA) protocol that accounts for the network traffic in mixed URLLC-mMTC scenarios. By considering an IoT environment under high mMTC traffic demand…
