Noncoherent MIMO in the FR3 Upper Mid-Band Using Grassmannian Signaling: Prototype and Experimental Evaluation
Álvaro Pendás-Recondo, Enrique Pendás-Recondo, Álvaro F. Vaquero +2
This work presents a prototype implementation of a noncoherent multiple-input multiple-output (MIMO) system based on Grassmannian signalling, where neither the transmitter nor rece…
A Structured Family of Grassmannian Constellations via Geodesic Mapping for MIMO Noncoherent Communications
Álvaro Pendás-Recondo, Enrique Pendás-Recondo
This work presents a novel structured family of Grassmannian constellations for multiple-input multiple-output (MIMO) noncoherent communications over Rayleigh block-fading channels…
Generalized Fermat's principle and Snell's law for cone structures and applications
Miguel Ángel Javaloyes, Steen Markvorsen, Enrique Pendás-Recondo +1
Fermat's principle is fully generalized to the case where a smooth interface separates two cone structures -- Lorentz-Finsler lightcones -- representing wave propagation in a poten…
Time-dependent Zermelo navigation with tacking
Steen Markvorsen, Enrique Pendás-Recondo, Frederik Möbius Rygaard
We address the time- and position-dependent Zermelo navigation problem within the framework of Lorentz-Finsler geometry. Since the initial work of E. Zermelo, the task is to find t…
On the application of Lorentz-Finsler geometry to model wave propagation
Enrique Pendás-Recondo
The recent increasing interest in the study of Lorentz-Finsler geometry has led to several applications to model real-world physical phenomena. Our purpose is to provide a simple,…
Gielis superformula and wildfire models
Miguel Ángel Javaloyes, Enrique Pendás-Recondo, Miguel Sánchez
Experimental data on the propagation of wildfires show that its short-time spread has a double semi-elliptical shape. Our main goal is to show that this shape can be accurately app…
Snell's law revisited and generalized via Finsler Geometry
Steen Markvorsen, Enrique Pendás-Recondo
We study the variational problem of finding the fastest path between two points that belong to different anisotropic media, each with a prescribed speed profile and a common interf…
An account on links between Finsler and Lorentz Geometries for Riemannian Geometers
Miguel Ángel Javaloyes, Enrique Pendás-Recondo, Miguel Sánchez
Some links between Lorentz and Finsler geometries have been developed in the last years, with applications even to the Riemannian case. Our purpose is to give a brief description o…
A general model for wildfire propagation with wind and slope
Miguel Ángel Javaloyes, Enrique Pendás-Recondo, Miguel Sánchez
A geometric model for the computation of the firefront of a forest wildfire which takes into account several effects (possibly time-dependent wind, anisotropies and slope of the gr…
Lightlike hypersurfaces and time-minimizing geodesics in cone structures
Miguel Ángel Javaloyes, Enrique Pendás-Recondo
Some well-known Lorentzian concepts are transferred into the more general setting of cone structures, which provide both the causality of the spacetime and the notion of cone geode…
