Adaptación al EEES de las prácticas de Electricidad y Electrónica de la E.T.S. de Náutica y Máquinas de la Universidade da Coruña mediante un diseño basado en competencias
(Universidade de Vigo, Facultade de Ciencias da Educacion, 2010)
[Summary] The adaptation to the European Higher Education Area (EHEA) of the subject of Electricity and Electronics at the Escuela Técnica Superior de Náutica y Máquinas of the University of A Coruña requires important ...
Channel estimation techniques for linear precoded systems: Supervised, unsupervised, and hybrid approaches
(Elsevier, 2011-07)
[Abstract] Linear precoding is an attractive technique to combat interference in multiple-input multiple-output systems because it reduces cost and power consumption at the receiver. Frequency division duplex systems with ...
Hybrid Channel Estimation Strategy for MIMO Systems with Decision Feedback Equalizer
(Springer, 2010)
[Abstract] We propose to combine supervised and unsupervised algorithms in order to improve the performance of multiple-input multiple-output digital communication systems which make use of differential feedback equalizers ...
Detection of channel variations to improve channel estimation methods
(Springer, 2014-08)
[Abstract] In current digital communication systems, channel information is typically
acquired by supervised approaches that use pilot symbols included in the transmit
frames. Given that pilot symbols do not convey user ...
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 ...
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 ...
Testbed-Assisted Learning for Digital Communications Courses
(John Wiley & Sons, 2013-09)
[Abstract] We introduce testbed-assisted learning as an effective means for teaching digital communications. Laboratory teaching activities of digital communications courses benefit very much from utilizing a hardware ...
Blind channel identification in Alamouti coded systems: a comparative study of eigendecomposition methods in indoor transmissions at 2.4 GHz
(Wiley, 2008)
[Abstract]: This paper focuses on blind channel estimation in Alamouti coded systems with one receiving antenna working in indoor scenarios where the flat fading assumption is reasonable. A comparative study of several ...
