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…
Cell-Free Massive MIMO-Assisted SWIPT for IoT Networks
Mohammadali Mohammadi, Le-Nam Tran, Zahra Mobini +2
This paper studies cell-free massive multiple-input multiple-output (CF-mMIMO) systems that underpin simultaneous wireless information and power transfer (SWIPT) for separate infor…
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…
Sensing Rate Optimization for Multi-Band Cooperative ISAC Systems
Nemanja Stefan Perović, Mark F. Flanagan, Le-Nam Tran
Integrated sensing and communication (ISAC) has been recognized as one of the key technologies for future wireless networks, which potentially need to operate in multiple frequency…
RIS-Aided Monitoring With Cooperative Jamming: Design and Performance Analysis
Shuying Lin, Yulong Zou, Zhiyang Li +3
We investigate a reconfigurable intelligent surface (RIS) aided wireless surveillance system. In this system, a monitor not only receives signal from suspicious transmitter via a R…
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…
