Digital Predistortion of Pseudo-Orthogonal Wideband Waveforms for Dual-Polarimetric Phased Array Radars
(2016-05)
Many new and interesting radar operational modes and techniques are being explored to maximize the efficiency and utility of next-generation radar systems while complying with increasingly stringent operational and budgeting ...
DIAMOND AND PARYLENE COMPOSITE BONDING: A POWERFUL METHOD FOR ELECTRONIC THIN FILM DEVICE FABRICATION
(2016-05-13)
A new and powerful method for electronic device fabrication is presented. A diamond and parylene composite thin film layer bonding process is described. Two sizes of diamond particles, nominally 0~0.5µm and 0~2µm were used ...
Investigation of a Frequency and Pattern Reconfigurable Slot Array Utilizing Ring Resonator End Loads
(2017-12)
Fixed-bandwidth wireless systems are forced to operate in preallocated blocks of frequencies, often wasting valuable spectrum. Whereas, systems with reconfigurable antennas that can tune resonant frequency, polarization, ...
Electromechanical Systems
(2018-12-19)
This eBook was written as the third installment in the series that coincide with three engineering courses taught at the University of Oklahoma (ENGR 2431, ENGR 2531, and ENGR 3431). These courses were designed to provide ...
Adaptive Localized Active Route Maintenance Mechanism to Improve Performance of VoIP over Ad Hoc Networks
(2011-02)
An important characteristic of a mobile ad hoc network routing protocol is connectivity maintenance. The protocol’s ability to maintain routes and react to topology changes due to link failures affects the delay, packet ...
Analysis of Backbone Technique: a Hilbert Transform and Discrete Hilbert Transform-based Technique
(2015-12)
This dissertation focuses on understanding and improving the “backbone” technique, a Hilbert-transform based vibration signal processing technique developed by Dr. Michael Feldman started in 1994. The concept of backbone ...
LOW-COST, SOFTWARE DEFINED FMCW RADAR FOR OBSERVATIONS OF DRONES
(2017-05-12)
This thesis focuses on implementing a small, low-cost, Frequency-Modulated-Continuous-Wave (FMCW) radar sensor using Software-Defined Radio (SDR) platforms. Extensive investigation and comparisons of existing SDRs are ...
Adaptive Distributed Source Coding Based on Bayesian Inference
(2015-08-14)
Distributed Source Coding (DSC) is an important topic for both in information theory and communication. DSC utilizes the correlations among the sources to compress data, and it has the advantages of being simple and easy ...
Ruggedized Feeding Techniques for Placement Insensitive Antennas
(2018-08-02)
Today's warfighter relies on extensive wireless technology to stay connected to allied forces and the battle theater. Communication equipment, IFF (identification friend-or-foe) identifiers, global positioning systems, ...
Video CODEC with adaptive frame rate control for intelligent transportation system applications
(2014-05)
Video cameras are one of the important types of devices in Intelligent Transportation Systems (ITS). The camera images are practical, widely deployable and beneficial for traffic management and congestion control. The ...
