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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
