Joint Optimal Bilinear Equalizer for Cell-Free Massive MIMO Systems With Multi-Antenna Users

Deep Unfolding for Joint Antenna Selection, Phase Shift Design, and Power Allocation in SIM-Assisted MU-MISO Systems

Stacked intelligent metasurfaces (SIMs) have emerged as a promising paradigm for wave-domain signal processing in next-generation wireless networks. In this paper, we investigate the joint optimization of antenna selection, SIM phase-shift design, and power allocation in SIM-assisted multiuser multiple-input single-out...

Joint Precoding, Passive Beamforming, and 3-D Trajectories Optimization for UAV-RISs-Assisted Systems With Statistical CSI

The combination of uncrewed aerial vehicles (UAVs) and reconfigurable intelligent surfaces (RISs) forms a cooperative framework that exploits the mutual advantages of both technologies. In this work, multiple RISs mounted on fixed-wing UAVs are adopted to adaptively reconfigure the transmission environments of communic...
