Impact of Channel Models on Performance Characterization of RIS-Assisted Wireless Systems
Vahid Jamali, Walid Ghanem, Robert Schober +1
The performance characterization of communication systems assisted by large reconfigurable intelligent surfaces (RISs) significantly depends on the adopted models for the underlyin…
Codebook Based Two-Time Scale Resource Allocation Design for IRS-Assisted eMBB-URLLC Systems
Walid R. Ghanem, Vahid Jamali, Malte Schellmann +3
This paper investigates the resource allocation algorithm design for wireless systems assisted by large intelligent reflecting surfaces (IRSs) with coexisting enhanced mobile broad…
Trajectory and Resource Optimization for UAV Synthetic Aperture Radar
Mohamed-Amine Lahmeri, Walid Ghanem, Christina Knill +1
In this paper, we study the trajectory and resource optimization for lightweight rotary-wing unmanned aerial vehicles (UAVs) equipped with a synthetic aperture radar (SAR) system.…
Optimization-based Phase-shift Codebook Design for Large IRSs
Walid R. Ghanem, Vahid Jamali, Malte Schellmann +3
In this paper, we focus on large intelligent reflecting surfaces (IRSs) and propose a new codebook construction method to obtain a set of pre-designed phase-shift configurations fo…
