A Novel Strategy for Improving the Quality of Embedded Zerotree Wavelet Images Transmitted over Alamouti Coding Systems

Labrador, Josmary; Castro-Castro, Paula-María; Pérez-Iglesias, Héctor J.; Dapena, Adriana (Springer, 2011)

[Abstract] This work deals with the transmission of images, previously coded using the Embedded Zerotree Wavelet (EZW) transform, over wireless systems in which Space-Time Coding (STC) is used. It is shown how the system ...
Hybrid Channel Estimation Strategy for MIMO Systems with Decision Feedback Equalizer

Pérez-Iglesias, Héctor J.; Dapena, Adriana; Castro-Castro, Paula-María; García-Naya, José A. (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

Castro-Castro, Paula-María; Pérez-Iglesias, Héctor J.; Dapena, Adriana; Castedo, Luis (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 ...
