Joint Spatial Division and Multiplexing for FDD in Intelligent Reflecting Surface-assisted Massive MIMO Systems
Papazafeiropoulos, Anastasios; Kourtessis, Pandelis; Ntontin, Konstantinos; Chatzinotas, Symeon (2022-06-30)Intelligent reflecting surface (IRS) is a promising technology to deliver the higher spectral and energy requirements in fifth-generation (5G) and beyond wireless networks while shaping the propagation environment. Such a ... -
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 ...
