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 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 Novel Strategy for Improving the Quality of Embedded Zerotree Wavelet Images Transmitted over Alamouti Coding Systems
(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 ...
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 ...
Measuring the physical layer performance of wireless communication systems: Part 33 in a series of tutorials on instrumentation and measurement
(Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2011-10)
[Abstract]: Measuring the physical layer performance of wireless radio communication systems is one important step in clearly understanding their behavior in real-world, that is, non-simulation, environments. Unfortunately, ...
