Multi-user ISAC through Stacked Intelligent Metasurfaces: New Algorithms and Experiments
Ziqing Wang, Hongzheng Liu, Jianan Zhang +5
This paper investigates a Stacked Intelligent Metasurfaces (SIM)-assisted Integrated Sensing and Communications (ISAC) system. An extended target model is considered, where the BS…
Optimization of RIS-Aided MIMO -- A Mutually Coupled Loaded Wire Dipole Model
H. El Hassani, X. Qian, S. Jeong +5
We consider a reconfigurable intelligent surface (RIS) assisted multiple-input multiple-output (MIMO) system in the presence of scattering objects. The MIMO transmitter and receive…
On the Degrees of Freedom of RIS-Aided Holographic MIMO Systems
Juan Carlos Ruiz-Sicilia, Xuewen Qian, Marco Di Renzo +3
In this paper, we study surface-based communication systems based on different levels of channel state information for system optimization. We analyze the system performance in ter…
Reconfigurable Intelligent Surface-Assisted Secret Key Generation in Spatially Correlated Channels
