    • Coverage Probability of STAR-RIS assisted Massive MIMO systems with Correlation and Phase Errors 

      Papazafeiropoulos, Anastasios; Abdullah, Zaid; Kourtessis, Pandelis; Kisseleff, Steven; Krikidis, Ioannis (2022-06-01)
      In this letter, we investigate a simultaneous transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) assisting a massive multiple-input multiple-output (mMIMO) system. In particular, we derive a closed-form ...

    • Impact of Phase-Noise and Spatial Correlation on Double-RIS-Assisted Multiuser MISO Networks 

      Abdullah, Zaid; Papazafeiropoulos, Anastasios; Kisseleff, Steven; Chatzinotas, Symeon; Ottersten, Bjorn (2022-05-17)
      We study the performance of a phase-noise impaired double reconfigurable intelligent surface (RIS)-aided multiuser (MU) multiple-input single-output (MISO) system under spatial correlation at both RISs and base-station ...

    • Wireless Energy Harvesting For Autonomous Reconfigurable Intelligent Surfaces 

      Ntontin, Konstantinos; Boulogeorgos, Alexandros Apostolos A.; Bjornson, Emil; Martins, Wallace Alves; Kisseleff, Steven; Abadal, Sergi; Alarcon, Eduard; Papazafeiropoulos, Anastasios; Lazarakis, Fotis; Chatzinotas, Symeon (2023-03-30)
      In the current contribution, we examine the feasibility of fully-energy-autonomous operation of reconfigurable intelligent surfaces (RIS) through wireless energy harvesting (EH) from incident information signals. Towards ...
