Incorporating HVDC's into monitoring and power system analysis
(Texas A&M University, 2002)
This thesis attempts to study the effect of incorporating HVDC's into monitoring and power system analysis. Power system analysis, including load flow and stability studies, and monitoring defines a complete cycle of the ...
Robust multiuser detection in α-stable distribution non-Gaussian noise
(Texas A&M University, 2002)
In this thesis, we will model the ambient non-Gaussian noise as the α-stable distribution because this model has many attractive properties. By using this noise model, the robust multiuser detectors achieve significant ...
Selection of wavelets for analysis of power system disturbances
(Texas A&M University, 2002)
The wavelet transform represents a powerful signal processing tool with a variety of applications. The main reason for the growing interest in this field of signal processing is its ability not only to decompose a signal ...
A 1.8V 2-2 cascade Sigma-Delta modulator for high speed applications
(Texas A&M University, 2002)
In order to satisfy today's most important requirements of the A/D and D/A converters that are low voltage and high speed operation, a low voltage and high speed circuit solutions for [] modulators are strongly demanding. ...
A channel estimation algorithm for Space Time OFDM systems on the Starcore SC140 DSP
(Texas A&M University, 2002)
This research implements an estimation scheme for a Space-Time OFDM system over a fading channel and evaluates the performance of the receiver using this scheme. The channel estimation problem for ST-OFDM is complex as the ...
Hierarchical classification of modulation signals
(Texas A&M University, 2002)
This thesis addresses the problem of classifying both analog and digital modulation signals using different kinds of classifiers. The classification of modulation signals has both civilian and military applications. A total ...
A compact broadband multilayer patch antenna and its applications for phased arrays
(Texas A&M University, 2002)
Phased arrays of antennas have found many applications in radio frequency and microwave frequency systems. One example of their use is in multibeam phased arrays for communications satellites. Patch antennas are well ...
An 8-bit current mode ripple folding analog to digital converter
(Texas A&M University, 2002)
Design of an 8-bit current mode, ripple-folding analog to digital (A/D) converter is discussed. The ripple folding technique and the possible implementations in different process technologies are summarized. To have an A/D ...
Charge pumping techniques in ultra-low current transconductor design
(Texas A&M University, 2002)
The purpose of this thesis is to introduce the use of interface-trap charge pumping devices (ITCP) in an analog application based in ultra-low-current transconductors. This application naturally exploits the continuous ...
