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 ...
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 ...
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 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 ...
Robust Precoding with Limited Feedback Design based on Precoding MSE for MU-MISO Systems
(Institute of Electrical and Electronics Engineers, 2012-06)
[Abstract] For the separation of the signals in the vector broadcast channel (BC), some information about the channel state is necessary at the transmitter. In many cases, this channel state information (CSI) must be fed ...
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 ...
A Practical Evaluation of a High-Security Energy-Efficient Gateway for IoT Fog Computing Applications
(M D P I AG, 2017-08-29)
[Abstract] Fog computing extends cloud computing to the edge of a network enabling new Internet of Things (IoT) applications and services, which may involve critical data that require privacy and security. In an IoT fog ...
A fog computing based cyber-physical system for the automation of pipe-related tasks in the Industry 4.0 shipyard
(M D P I AG, 2018-06-17)
[Abstract] Pipes are one of the key elements in the construction of ships, which usually contain between 15,000 and 40,000 of them. This huge number, as well as the variety of processes that may be performed on a pipe, ...
A practical evaluation on RSA and ECC-based cipher suites for IoT high-security energy-efficient Fog and mist computing devices
(M D P I AG, 2018-11-10)
[Abstract] The latest Internet of Things (IoT) edge-centric architectures allow for unburdening higher layers from part of their computational and data processing requirements. In the specific case of fog computing systems, ...
Optimal Synthesis of Line Source Antennas Based On Rhodes Distributions
(Taylor & Francis, 2002)
[Abstract] In this paper we show that by means of an appropriate optimization technique the zeros of Rhodes radiation patterns can be perturbed so as to improve or modify pattern and/or the aperture distribution characteristics ...
