SISTEMA MIMO EMPLEANDO ANTENAS ADAPTATIVAS
Telemática, 2013 La utilización de múltiples antenas tanto en transmisión como en recepción sobre un enlace radio conlleva un aumento de la capacidad teórica del canal Multiple-Input Multiple-Output (MIMO) resultante. Este hecho abre el camino hacia la obtención de altas

IET Communications, Volume 17, Issue 9, Page 1118-1126, June 2023., 2023 Low cost video sensors used to help firefighters, require high bit rate. To increase spectral efficiency given a limited bandwidth, high order constellations can be used. These constellations are sensitive to hardware impairments. Therefore, this paper studies the effect of carrier frequency offset on the performance of an orthogonal frequency division

Electronics Letters, Volume 58, Issue 20, Page 779-782, September 2022., 2022 Abstract The foreseen scale of connected autonomous and low power consumption devices in the near future is a challenging aspect for the next generation of mobile communication networks. As the number of available connection resources is limited, frequency‐time multiplexing may not be sufficient to meet the expected demand for capacity, where ...

A QFT approach to robust dual‐rate control systems
International Journal of Robust and Nonlinear Control, Volume 32, Issue 2, Page 1026-1054, 25 January 2022., 2022 Abstract A dual‐rate control system is a hybrid system composed of continuous‐time and discrete‐time elements with two sampling frequencies. In this work, a new frequency domain analysis and design approach, based on the quantitative feedback theory is developed, to cope with robust stability and robust tracking specifications.

Filling Control of a Conical Tank Using a Compact Neuro‐Fuzzy Adaptive Control System
Complexity, Volume 2022, Issue 1, 2022., 2022 This document describes the implementation of a conical tank control system using an adaptive neurofuzzy system. For implementation, an indirect approach is used where the controller is optimized using the model obtained during the plant identification carried out using data obtained during the system operation.
