Spatial Limits of Fluid Antenna Systems
Amy S. Inwood, Peter J. Smith, Rajitha Senanayake +1
Continuous fluid antenna systems (CFASs) represent an upper bound on the spatial diversity performance of fluid antenna systems (FASs), achieved when antennas may be positioned any…
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…
Deep Learning-Based Computer Vision for Beam Selection and Proactive Blockage Prediction
Sachira Karunasena, Erfan Khordad, Tom Drummond +1
Millimeter-wave communication faces two critical challenges: propagation losses requiring costly narrow-beam alignment, and penetration losses causing link failures from blocked li…
A Robust Nonparametric Framework for Detecting Repeated Spatial Patterns
Rajitha Senanayake, Pratheepa Jeganathan
Identifying spatially contiguous clusters and repeated spatial patterns (RSP) characterized by similar underlying distributions that are spatially apart is a key challenge in moder…
Beam Squinting Effects in Super Wideband Communication Systems
Sachitha C. Bandara, Peter J. Smith, Erfan Khordad +3
Beam squint, the frequency-dependent shift of the main beam, poses a major challenge for wideband antenna arrays. This paper focuses on the beam squint effects in super wideband (S…
