Practical Challenges for Reliable RIS Deployment in Heterogeneous Multi-Operator Multi-Band Networks
Mehdi Monemi, Mehdi Rasti, Arthur S. de Sena +3
Reconfigurable intelligent surfaces (RISs) have been introduced as arrays of nearly passive elements with software-tunable electromagnetic properties to dynamically manipulate the…
Machine Learning-Based Channel Prediction for RIS-assisted MIMO Systems With Channel Aging
Nipuni Ginige, Arthur Sousa de Sena, Nurul Huda Mahmood +2
Reconfigurable intelligent surfaces (RISs) have emerged as a promising technology to enhance the performance of sixth-generation (6G) and beyond communication systems. The passive…
Malicious RIS versus Massive MIMO: Securing Multiple Access against RIS-based Jamming Attacks
Arthur Sousa de Sena, Jacek Kibilda, Nurul Huda Mahmood +2
In this letter, we study an attack that leverages a reconfigurable intelligent surface (RIS) to induce harmful interference toward multiple users in massive multiple-input multiple…
Beyond Diagonal RIS for Multi-Band Multi-Cell MIMO Networks: A Practical Frequency-Dependent Model and Performance Analysis
Arthur S. de Sena, Mehdi Rasti, Nurul H. Mahmood +1
This paper delves into the unexplored frequency-dependent characteristics of beyond diagonal reconfigurable intelligent surfaces (BD-RISs). A generalized practical frequency-depend…
