Channel Estimation and Reconstruction in Fluid Antenna Multiple Access: Myths, Misconceptions and Critical Questions
Taissir Y. Elganimi, Pablo Ramírez-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…
Implementing Fluid Antennas in the Beamspace: Performance Evaluation and Codebook Design
Pablo Ramírez-Espinosa, F. Javier López-Martínez, David Morales-Jiménez
Metasurface-based fluid antenna systems (FASs) have been recently proposed as an inexpensive, scalable and practical alternative implementation for the fluid-antenna concept. This…
Metasurface-based Fluid Antennas: from Electromagnetics to Communications Model
Pablo Ramírez-Espinosa, Cleofás Segura-Gómez, Ángel Palomares-Caballero +2
Fluid antenna systems (FASs) have become a popular topic in the wireless community as an effective yet simple means of exploiting spatial diversity. Due to the limitations of physi…
Energy efficiency of DMAs vs. conventional MIMO: a sensitivity analysis
Pablo Ramírez-Espinosa, David Morales-Jiménez, Beatriz Soret
Motivated by the stringent and challenging need for `greener communications' in increasingly power-hungry 5G networks, this paper presents a detailed energy efficiency analysis for…
