    • Scalable cell-free massive MIMO systems with hardware impairments 

      Papazafeiropoulos, A. K.; Bjornson, Emil; Kourtessis, P.; Chatzinotas, S.; Senior, John M. (Institute of Electrical and Electronics Engineers (IEEE), 2020-10-08)
      Despite the deleterious effect of hardware impairments (HWIs) on wireless systems, most prior works in cell-free (CF) massive multiple-input-multiple-output (mMIMO) systems have not accounted for their impact. In particular, ...

    • 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 ...
