RIS-Aided ISAC in Cluttered Environments
Yosefine Triwidyastuti, Tri Nhu Do, Ngo Hoang Tu +1
In this paper, we analyze the performance of a communication-optimized reconfigurable intelligent surface (RIS)-assisted integrated sensing and communication (ISAC) system operatin…
QoS-Aware Energy Optimization via Cell Switching in Heterogeneous Networks
Maryam Salamatmoghadasi, Amir Mehrabian, Halim Yanikomeroglu +1
The growing demand for mobile data services in dense urban areas has intensified the need for energy-efficient radio access networks (RANs) in future 6G systems. In this context, o…
Sustainable Vertical Heterogeneous Networks: A Cell Switching Approach with High Altitude Platform Station
Maryam Salamatmoghadasi, Amir Mehrabian, Halim Yanikomeroglu +1
The rapid growth of radio access networks (RANs) is increasing energy consumption and challenging the sustainability of future systems. We consider a dense-urban vertical heterogen…
Beamforming for Massive MIMO Aerial Communications: A Robust and Scalable DRL Approach
Hesam Khoshkbari, Georges Kaddoum, Omid Abbasi +2
This paper presents a distributed beamforming framework for a constellation of airborne platform stations (APSs) in a massive Multiple-Input and Multiple-Output (MIMO) non-terrestr…
Distributed Beamforming in Massive MIMO Communication for a Constellation of Airborne Platform Stations
Hesam Khoshkbari, Georges Kaddoum, Bassant Selim +2
Non-terrestrial base stations (NTBSs), including high-altitude platform stations (HAPSs) and hot-air balloons (HABs), are integral to next-generation wireless networks, offering co…
Cooperative Jamming Detection Using Low-Rank Structure of Received Signal Matrix
Amir Mehrabian, Georges Kaddoum
Wireless communication can be simply subjected to malicious attacks due to its open nature and shared medium. Detecting jamming attacks is the first and necessary step to adopt the…
