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 ...
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 ...
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 ...
Continuous time very low frequency analog signal processors
(Texas A&M University, 2000)
In this work, basic analog integrated circuits such as integrators, multipliers, comparators, summers and impedance scaling networks which serve as the basic building blocks for designing complicated continuous time analog ...
Fiber optic temperature sensor using a grating on an angled fiber tip
(Texas A&M University, 2000)
A fiber optic temperature sensor intended to sense temperatures up to 1400°C was investigated experimentally. A key element of the sensor is a grating on the 45°-angled tip of a single mode fiber. When light propagating ...
Signal processing for fiber optic acoustic sensor system
(Texas A&M University, 2000)
A new scheme for optic detection of sound waves based upon fiber optic interferometer is presented. Multiple fiber Fabry-Perot interferometers (FFPI) are used as arrayed sensor elements inside the cable. The sensors are ...
A physical approach to metal insulator metal (MIM) tuning capacitor modeling
(Texas A&M University, 2000)
Due to the extensive use of capacitors both as tuning and RF bypass elements in monolithic integrated circuit (MMIC) design, it becomes increasingly important to accurately predict the performance of such structures in ...
Wavelet-based progressive image and video coding using trellis-coded space-frequency quantization
(Texas A&M University, 2000)
Images and video are a very challenging topic in multimedia applications. Recently, with the explosion of the Internet, multiresolution source codes are necessary to better suit to the heterogeneity of the networks. This ...
A smart camera application: DSP-based people detection and tracking
(Texas A&M University, 2000)
As an application of smart cameras, this thesis presents an algorithm and its real-time implementation for detecting and tracking multiple people moving in a surveillance scene. The algorithm is devised to work for low ...
