Precoding for Multi-Cell ISAC: from Coordinated Beamforming to Coordinated Multipoint and Bi-Static Sensing
Nithin Babu, Christos Masouros, Constantinos B. Papadias +1
This paper proposes a framework for designing robust precoders for a multi-input single-output (MISO) system that performs integrated sensing and communication (ISAC) across multip…
Energy-Efficient Trajectory Design of a Multi-IRS Assisted Portable Access Point
Nithin Babu, Marco Virgili, Mohammad Al-jarrah +6
In this work, we propose a framework for energy-efficient trajectory design of an unmanned aerial vehicle (UAV)-based portable access point (PAP) deployed to serve a set of ground…
Cost-Efficient Deployment of a Reliable Multi-UAV Unmanned Aerial System
Nithin Babu, Petar Popovski, Constantinos B. Papadias
In this work, we study the trade-off between the reliability and the investment cost of an unmanned aerial system (UAS) consisting of a set of unmanned aerial vehicles (UAVs) carry…
Fairness Based Energy-Efficient 3D Path Planning of a Portable Access Point: A Deep Reinforcement Learning Approach
Nithin Babu, Igor Donevski, Alvaro Valcarce +3
In this work, we optimize the 3D trajectory of an unmanned aerial vehicle (UAV)-based portable access point (PAP) that provides wireless services to a set of ground nodes (GNs). Mo…
On the Robustness of Coordinated Beamforming to Uncoordinated Interference and CSI Uncertainty
George C. Alexandropoulos, Paul Ferrand, Constantinos B. Papadias
As network deployments become denser, interference arises as a dominant performance degradation factor. To confront with this trend, Long Term Evolution (LTE) incorporated features…
Precoding for Multiuser MIMO Systems with Single-Fed Parasitic Antenna Arrays
George C. Alexandropoulos, Vlasis I. Barousis, Constantinos B. Papadias
Transmitter (TX) cooperation at various levels has been shown to increase the sum throughput of multiuser multiple-input multiple-output (MIMO) systems. In this paper we consider a…
