Hybrid Supervised-Unsupervised Channel Estimation Scheme with Dynamic Transmission of Pilots
(Springer, 2011-02)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards typically include pilot symbols in the definition of the transmit signals with the purpose of acquiring the Channel State Information (CSI) ...
A low-cost decision-aided channel estimation method for Alamouti OSTBC
(Springer, 2013-11)
[Abstract] In wireless communication systems, channel state information (CSI) acquisition is typically performed at the receiver side every time a new frame is received, without taking into account whether it is really ...
A Novel Strategy for Improving the Quality of Embedded Zerotree Wavelet Images Transmitted over Alamouti Coding Systems
(Springer, 2011)
[Abstract] This work deals with the transmission of images, previously coded using the Embedded Zerotree Wavelet (EZW) transform, over wireless systems in which
Space-Time Coding (STC) is used. It is shown how the system ...
Brain-Computer Interfaces for Internet of Things
(M D P I AG, 2018-09-17)
[Abstract] A brain-computer interface for controlling elements commonly used at home is presented in this paper. It includes the electroencephalography device needed to acquire signals associated to the brain activity, the ...
Aplicación web para evaluación y seguimiento del rendimiento de asignaturas y titulaciones universitarias
(Universidade de Vigo, Facultade de Ciencias da Educacion, 2010)
[Summary] The adaptation of the university studies to the current European Higher Education Area (EHEA) requires the set up of mechanisms, which allow performance evaluation of the subjects compounding the new university ...
A MATLAB Tool for Visualizing the 3D Polar Power Patterns and Excitations of Conformal Arrays
(Institute of Electrical and Electronics Engineers, 2010-08)
[Abstract] This paper describes the implementation of a MATLAB® tool to plot the three-dimensional polar radiation diagram generated by a conformal antenna array. A related tool has also been developed for visualizing the ...
A Comparative Study of Low Cost Open Source EEG Devices
(MDPI AG, 2019-08-05)
[Abstract] A comparison of two open source electroencephalography devices designed to acquire signals associated to the brain activity is presented in this work. The experiments are developed considering the task of ...
A Prototype of EEG System for IoT
(World Scientific Publishing Co. Pte. Ltd., 2020-05-04)
[Abstract] In this work, we develop open source hardware and software for eye state classification and integrate it with a protocol for the Internet of Things (IoT). We design and build the hardware using a reduced number ...
Isolation Number versus Domination Number of Trees
(MDPI, 2021-06)
[Abstract] If 𝐺 = (Vɢ,Eɢ) is a graph of order n, we call 𝑆 ⊆ Vɢ an isolating set if the graph induced by Vɢ − Nɢ[𝑆] contains no edges. The minimum cardinality of an isolating set of 𝐺 is called the isolation number of ...
Development of Recreational Content with Micro:Bit for Intervention with People with Cerebral Palsy
(MDPI, 2020-09-04)
[Abstract]
This paper presents a project carried out to use games in therapies for people with cerebral
palsy. A Micro:bit board is used to have a friendly interaction between the user and the game.
Through a simple ...
