Utilization of Blind Source Separation Algorithms for MIMO Linear Precoding
(Springer, 2006)
[Abstract] In this paper we investigate the application of Blind Source Separation (BSS) algorithms for the decoding of linearly precoded MIMO communication systems and for the design of limited feedback channels that send ...
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 ...
Vehicle Classification using the Discrete Fourier Transform with Traffic Inductive Sensors
(Multidisciplinary Digital Publishing Institute, 2015)
[Abstract] Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management systems. This paper shows that some spectral features extracted from the Fourier Transform (FT) of inductive signatures ...
SiDIVS: Simple Detection of Inductive Vehicle Signatures with a Multiplex Resonant Sensor
(Multidisciplinary Digital Publishing Institute, 2016)
This work provides a system capable of obtaining simultaneous inductive signatures of vehicles traveling on a roadway with minimal cost. Based on Time-Division Multiplexing (TDM) with multiple oscillators, one for each ...
Inductive loops for traffic control
(2015-09)
Inductive Loop Detectors (ILDs) are the most commonly used sensors in traffic management
systems. This work provides a system capable of obtaining simultaneous inductive
signatures of vehicles traveling on a roadway with ...
Calculation of the Connected Dominating Set Considering Vertex Importance Metrics
(M D P I AG, 2018-01-28)
[Abstract] The computation of a set constituted by few vertices to define a virtual backbone supporting information interchange is a problem that arises in many areas when analysing networks of different natures, like ...
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) ...
