Improved SINR Approximation for Downlink RSMA-based Networks with Outdated Channel State Information
Maria Cecilia Fernández Montefiore, Gustavo González, F. Javier López-MartÃnez +1
The paper proposes a more accurate statistical approximation of the downlink SINR for multi‑user MIMO systems when the transmitter has outdated channel state information, and valid…
Channel Estimation and Reconstruction in Fluid Antenna Multiple Access: Myths, Misconceptions and Critical Questions
Taissir Y. Elganimi, Pablo RamÃrez-Espinosa, David Morales-Jiménez +1
Fluid antenna systems (FAS) represent a paradigm shift in which antenna elements (ports) emulate the illusion of motion or fluidity within a spatial aperture to optimize performanc…
Hybrid Multiport Receivers for Slow Fluid Antenna Multiple Access
José P. González-Coma, José David Vega-Sánchez, F. Javier López-MartÃnez
We propose a novel receiver architecture that preserves the performance benefits of multiport selection in fluid-antenna systems while requiring only a very small number of radio-f…
Copula-Induced Correntropy for Robust Conjugate Gradient Learning
Farshad Rostami Ghadi, F. Javier Lopez-Martinez, David Morales-Jimenez +2
Robust learning in the presence of non-Gaussian and statistically dependent noise remains a fundamental challenge in signal processing and adaptive systems. Although information-th…
Greedy and Transformer-Based Multi-Port Selection for Slow Fluid Antenna Multiple Access
Darian Perez-Adan, Jose P. Gonzalez-Coma, F. Javier Lopez-Martinez +1
We address the port-selection problem in fluid antenna multiple access (FAMA) systems with multi-port fluid antenna (FA) receivers. Existing methods either achieve near-optimal spe…
AI-Limited Fluid Antenna-Aided Integrated Sensing and Communication Systems
Farshad Rostami Ghadi, Kai-Kit Wong, F. Javier Lopez-Martinez +3
This paper characterizes the fundamental limits of integrated sensing and communication (ISAC) when the transmitter is subject to an artificial intelligence (AI) representation bot…
