VineSens: An Eco-Smart Decision-Support Viticulture System
(M D P I AG, 2017-02-25)
[Abstract] This article presents VineSens, a hardware and software platform for supporting the decision-making of the vine grower. VineSens is based on a wireless sensor network system composed by autonomous and self-powered ...
Performance of MIMO systems in measured indoor channels with transmitter noise
(Springer, 2012)
This study analyzes the impact of transmitter noise on the performance of multiple-input multiple-output (MIMO) systems with linear and nonlinear receivers and precoders. We show that the performance of MIMO linear and ...
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 ...
Transmission of Still Images Using Low-Complexity Analog Joint Source-Channel Coding
(M D P I AG, 2019-07-03)
[Abstract] An analog joint source-channel coding (JSCC) system designed for the transmission of still images is proposed and its performance is compared to that of two digital alternatives which differ in the source encoding ...
Analog Video Encoding and Quality Evaluation
(M D P I AG, 2019-07-23)
[Abstract] The most widespread analog video encoding systems in the literature are based on the use of the 2D and 3D DCT. These systems use both transformations indistinctly without assessing their suitability. In this ...
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 ...
A plug-and-play human-centered virtual TEDS architecture for the web of things
(M D P I AG, 2018-06-27)
[Abstract] This article presents a Virtual Transducer Electronic Data Sheet (VTEDS)-based framework for the development of intelligent sensor nodes with plug-and-play capabilities in order to contribute to the evolution ...
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 ...
Robust Precoding with Bayesian Error Modeling for Limited Feedback MU-MISO Systems
(IEEE, 2010)
[Abstract] We consider the robust precoder design for multiuser multiple-input single-output (MU-MISO) systems where the channel state information (CSI) is fed back from the single antenna receivers to the centralized ...
