Intelligent Omni-Surfaces (IOSs) for the MIMO Broadcast Channel
Abdelhamed Mohamed, Nemanja Stefan Perović, Marco Di Renzo
In this paper, we consider intelligent omni-surfaces (IOSs), which are capable of simultaneously reflecting and refracting electromagnetic waves. We focus our attention on the mult…
Joint CFO and Channel Estimation for RIS-aided Multi-user Massive MIMO Systems
Sumin Jeong, Arman Farhang, Nemanja Stefan Perović +1
Accurate channel estimation is essential to achieve the performance gains promised by the use of reconfigurable intelligent surfaces (RISs) in wireless communications. In the uplin…
On the Maximum Achievable Sum-rate of the RIS-aided MIMO Broadcast Channel
Nemanja Stefan Perović, Le-Nam Tran, Marco Di Renzo +1
Reconfigurable intelligent surfaces (RISs) represent a new technology that can shape the radio wave propagation and thus offers a great variety of possible performance and implemen…
