Analysis of Fluid Antenna Systems with Continuous Positioning and Spatial Correlation
Gayani Siriwardana, Peter J. Smith, Himal A. Suraweera +1
We analyze multi-user fluid antenna systems with continuous positioning over a track of length L under a spatial correlation model, where exact performance distributions become ana…
Performance Analysis of Movable Antenna Arrays
Gayani Siriwardana, Peter J. Smith, Himal A. Suraweera +1
This paper provides a thorough mathematical analysis of continuous movable antenna (MA) arrays. Focusing on the multiple antenna case, we consider a linear antenna array with multi…
Repeater-Assisted Massive MIMO Full-Duplex Communications
Mohammadali Mohammadi, Dhanushka Kudathanthirige, Himal A. Suraweera +2
We consider a wireless network comprising multiple singleantenna repeaters that amplify and instantaneously re-transmit received signals in a full-duplex (FD) communication setting…
Chaotic Noncoherent SWIPT in Multi-Functional RIS-Aided Systems
Priyadarshi Mukherjee, Constantinos Psomas, Himal A. Suraweera +1
In this letter, we investigate the design of chaotic signal-based transmit waveforms in a multi-functional reconfigurable intelligent surface (MF-RIS)-aided set-up for simultaneous…
DRL-AdaPart: DRL-Driven Adaptive STAR-RIS Partitioning for Fair and Frugal Resource Utilization
Ashok S. Kumar, Nancy Nayak, Sheetal Kalyani +1
In this work, we propose a method for efficient resource utilization of simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) elements to ensure…
Damage Assessment after Natural Disasters with UAVs: Semantic Feature Extraction using Deep Learning
Nethmi S. Hewawiththi, M. Mahesha Viduranga, Vanodhya G. Warnasooriya +4
Unmanned aerial vehicle-assisted disaster recovery missions have been promoted recently due to their reliability and flexibility. Machine learning algorithms running onboard signif…
