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 ...
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 ...
DASBE: Decision-Aided Semi-Blind Equalization for MIMO Systems with Linear Precoding
(Akademie Ved Ceske Republiky * Ustav Informatiky, 2010)
[Abstract] Multiple-Input Multiple-Output (MIMO) digital communications standards usually acquire Channel State Information (CSI) by means of supervised algorithms, which implies a loss of performance since pilot symbols ...
A Novel Hybrid Approach to Improve Performance on Frequency Division Duplex Systems with Linear Precoding
(Springer, 2010)
[Abstrtact] Linear precoding is an attractive technique to combat interference in multiple-input multiple-output systems because it reduces costs and power consumption in the receiver equipment. Most of the frequency ...
A Novel Criterion for Vehicle Classification using Inductive Vehicle Signatures
(Institute of Research Engineers and Doctors (IRED), 2016-04)
[Abstract]: Inductive Loop Detectors (ILD) are the most
commonly used sensors in traffic management systems. Using
the acquired inductive signatures, most proposed systems
classify the vehicles using a criterion based ...
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 ...
Evaluation of H.264/AVC over IEEE 802.11p vehicular networks
(SpringerOpen & European Association for Signal Processing, 2013)
[Abstract]: The capacity of vehicular networks to offer non-safety services, like infotainment applications or the exchange of multimedia information between vehicles, have attracted a great deal of attention to the field ...
Real-time multimedia coding and transmission
(SpringerOpen & European Association for Signal Processing, 2013)
[Abstract]: This paper sums up relevant topics covered by the special issue titled ‘Real-Time Multimedia Coding and Transmission’, including efficient content representation, multimedia transmission, hardware and software ...
