A fault location approach for fuzzy fault section estimation on radial distribution feeders
(Texas A&M University, 2000)
Locating the faulted section of a distribution system is a difficult task because of lack of accurate system models and the presence of uncertainty in the data used for estimating the fault section. Many of the methods ...
Kalman filter based MMSE receiver for the DS-CDMA system in a Rayleigh fading channel
(Texas A&M University, 2000)
MMSE based detectors are studied as receivers for DS-CDMA systems for their ease of implementation and their ability to be implemented with adaptive algorithms. The adaptive algorithms helps the receiver in adjusting to ...
A Bragg grating on LiNbO₃ waveguide for velocity-matching of electrooptic modulators
(Texas A&M University, 2001)
An experimental study of the fabrication of a surface grating in a TiO₂ film on a LiNbO₃ substrate is described. Such a grating can be used to achieve velocity-matching between an optical wave and a RF signal in a slow-wave ...
Nonlinear adaptive internal model control using neural networks
(Texas A&M University, 2001)
The IMC structure, where the controller implementation includes an explicit model of the plant, has been shown to be very effective for the control of the stable plants typically encountered in process control. A nonlinear ...
System level design and simulation of a PCM voiceband modem compliant with the ITU V.90 standard
(Texas A&M University, 2000)
The present work is aimed towards an analysis of the ITU-T V.90 standard. Functionally, the system is divided into three main areas: Constellation Design, Spectral Shaping, and Detection. A signal constellation design ...
Improving service availability during link failure transients through alternate routing
(Texas A&M University, 2003)
A link failure in a network results in interruption of service for many end users. Currently, routers observing a link failure, recompute their routing tables to find new routes around the failure. However, the network ...
Bayesian multiuser detection for CDMA with nonlinear modulation
(Texas A&M University, 2000)
This study introduces a blind iterative multiuser detection scheme for demodulating nonlinearly modulated CDMA signals in Gaussian and non-Gaussian noise, based on the Bayesian inference. The detector jointly estimates the ...
Implementation of ITU-T V.90 standard PCM modem in TMS320C6201 digital signal processor
(Texas A&M University, 2001)
In this thesis work, the basic functionality of a ITU-T Standard V.90 modem is implemented in a TMS320C6201 Digital Signal Processor (DSP). The encoder, equalizer and decoder functions of a V.90 modem are programmed in the ...
Design of oversampling current steering DAC with 640MHz equivalent clock frequency
(Texas A&M University, 2002)
A DAC (Digital-to-Analog Converter) architecture based on the current steering method is proposed. The architecture exploits the first order sigma-delta modulator, oversampling technique, multi-bit and MASH (multi stage ...
Combined wavelet video coding and error control for internet streaming and multicast
(Texas A&M University, 2002)
In the past several years, advances in Internet video streaming have been tremendous. Originally designed without error protection, Receiver-driven layered multicast (RLM) has proved to be a very effective scheme for ...
