Multi-Sensor Accurate Forklift Location and Tracking Simulation in Industrial Indoor Environments
(M D P I AG, 2019-10-12)
[Abstract] Location and tracking needs are becoming more prominent in industrial environments nowadays. Process optimization, traceability or safety are some of the topics where a positioning system can operate to improve ...
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 ...

(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 ...
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 ...
A MATLAB Interface for Analyzing Conformal Arrays Composed of Polarized Heterogeneous Elements
(Institute of Electrical and Electronics Engineers, 2011-10)
[Abstract] As an extension and improvement of a previous work, this paper presents a graphical interface designed with MATLAB®, which is capable of representing both the spatial and electrical configurations of a conformal ...
