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 ...
Analog free-space optical links.
(2005)
Free-space optics (FSO) communications is a technology that uses modulated infrared optical beams to transmit information line-of-sight through the atmosphere. There has been a substantial increase in the use of FSO ...
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, ...
Performance evaluation of the third generation TD-SCDMA system.
(2004)
Firstly, a basic reverse TD-SCDMA system is setup, including a transmitter, a receiver and a channel. Within the receiver model, a specific soft Viterbi decoding algorithm is developed. Secondly, the system synchronization ...
PRACTICAL COUGH DETECTION IN PRESENCE OF BACKGROUND NOISE AND PRELIMINARY DIFFERENTIAL DIAGNOSIS FROM COUGH SOUND USING ARTIFICIAL INTELLIGENCE
(2020-05-07)
Cough is one of the most common symptoms for many of the diseases. Physicians have been using characteristics of cough for preliminary diagnosis of certain respiratory diseases for ages. But the methods have been subjective ...
Performance enhancement of large scale networks with heterogeneous traffic.
(2006)
Finally, these findings are applied towards improving the performance of the Differentiated Services architecture by developing a new Refined Assured Forwarding framework where heterogeneous traffic flows share the same ...
A high-performance inner-product processor for real and complex numbers.
(2003)
A novel, high-performance fixed-point inner-product processor based on a redundant binary number system is investigated in this dissertation. This scheme decreases the number of partial products to 50%, while achieving ...
