STAR Beyond Diagonal RISs with Amplification: Modeling and Optimization
Chandan Kumar Sheemar, Giovanni Iacovelli, Wali Ullah Khan +3
This paper develops a physically consistent signal model with hardware constraints for a simultaneous transmitting and reflecting beyond-diagonal RIS (STAR BD-RIS) endowed with per…
Digital Twin-Based Beamforming for Interference Mitigation in AF Relay MIMO Systems
Alexander Bonora, Anna V. Guglielmi, Davide Scazzoli +4
Beamforming in multiple-input multiple-output (MIMO) systems should take interference mitigation into account. However, for beamform design, accurate channel state information (CSI…
User Localization with HRIS and Backscatter Modulation for Next-Generation Networks
Mattia Piana, Stefano Tomasin
Hybrid reflective intelligent surfaces (HRISs) can support localization in sixth-generation (6G) networks thanks to their ability to generate narrow beams and at the same time rece…
Scheduling for Downlink OFDMA With IRS Reconfiguration Constraints
Alberto Rech, Leonardo Badia, Stefano Tomasin
The technical limitations of the intelligent reflecting surface (IRS) (re)configurations in terms of both communication overhead and energy efficiency must be considered when IRSs…
