A Refined Alternating Optimization for Sum Rate Maximization in SIM-Aided Multiuser MISO Systems
Eduard E. Bahingayi, Shuying Lin, Murat Uysal +2
Stacked intelligent metasurfaces (SIMs) have emerged as a disruptive technology for future wireless networks. To investigate their capabilities, we study the sum rate maximization…
Power-Efficient Deceptive Wireless Beamforming Against Eavesdroppers
Georgios Chrysanidis, Antonios Argyriou, Le-Nam Tran +2
Eavesdroppers of wireless signals want to infer as much as possible regarding the transmitter (Tx). Popular methods to minimize information leakage to the eavesdropper include cove…
Scaling Achievable Rates in SIM-aided MIMO Systems with Metasurface Layers: A Hybrid Optimization Framework
Eduard E. Bahingayi, Nemanja Stefan Perović, Le-Nam Tran
We investigate the achievable rate (AR) of a stacked intelligent metasurface (SIM)-aided holographic multiple-input multiple-output (HMIMO) system by jointly optimizing the SIM pha…
On the Joint Beamforming Design for Large-scale Downlink RIS-assisted Multiuser MIMO Systems
Eduard E. Bahingayi, Nemanja Stefan Perović, Le-Nam Tran
Reconfigurable intelligent surfaces (RISs) have huge potential to improve spectral and energy efficiency in future wireless systems at a minimal cost. However, early prototype resu…
Securing FC-RIS and UAV Empowered Multiuser Communications Against a Randomly Flying Eavesdropper
Shuying Lin, Yulong Zou, Yuhan Jiang +3
This paper investigates a wireless network consisting of an unmanned aerial vehicle (UAV) base station (BS), a fully-connected reconfigurable intelligent surface (FC-RIS), and mult…
