Structural Test bench Development for DSP Models

Abstract :-
The objective of this thesis is the development of a set of library models from which a structural test bench can be created. This thesis also describes creation of the structural test bench using the library of primitive components and Synopsis Graphical Environment, a conventional schematic capture tool. This approach has been implemented for two applications Continue reading Structural Test bench Development for DSP Models

Synthesis and Characterization of Magnetic II-VI Nanoparticles

Abstract :-
Magnetic semiconductor nanocrystals are being studied for their potential application in the field of spintronics as spin-injectors for spin-based transistors and spin-based storage elements for nonvolatile memories. They also have a number of biomedical engineering applications including contrast enhancing agents for magnetic resonance imaging (MRI).

Use of Fuzzy Logic to control paralleled DC-DC converters

Abstract :-
The objective of the thesis is to introduce a new fuzzy logic control application, develop the associated mathematical theory and prove the concept and its advantages through comparative simulation with existing, classical, methods. A stable fuzzy logic controller for the master-slave current sharing loop of a paralleled DC-DC system is presented that exhibits a considerably improved large signal performance over the presently employed, small signal designed compensators, both in terms of system response and control effort. Because of high system complexity, the present small signal designs are unable to give a good response for large load changes and line transients.

Evaluation of TDOA Techniques for Position Location in CDMA Systems

Abstract :-
This thesis analyzes the performance of TDOA techniques in the CDMA systems. A comparison and assessment of different algorithms for finding the time difference estimates and for solving the hyperbolic equations generated by those estimates has been made. This research also considers a measure of accuracy for TDOA position location method which is shown to be more suitable for CDMA systems and more closely matches to the FCC requirements. Among the other contributions is a proposed method to perform cross-correlations to identify only the desired user’s TDOA in a multiuser environment.
