Some contributions to asymmetric error control codes

Creator:: Elmougy, Samir
Abstract:: In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...

Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

Creator:: Thuan Nguyen D.
Abstract:: There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

Time and statistical information utilization in high efficiency sub-micron CMOS successive approximation analog to digital converters

Creator:: Guerber, Jon
Abstract:: In an industrial and consumer electronic marketplace that is increasingly demanding greater real-world interactivity in portable and distributed devices, analog to digital converter efficiency and performance is being carefully examined. The successive approximation (SAR) analog to digital converter (ADC) architecture has become popular for its high efficiency at mid-speed and...

Modeling and analysis of spur structure of digital-to-time conversion based frequency synthesizers

Creator:: Talwalkar, Sumit A.
Abstract:: Frequency synthesizers are critical components of all communication systems. This thesis considers the issue of undesirable frequency spurs of a relatively recent type of frequency synthesis architecture called digital-to-time conversion (DTC). The DTC-based frequency synthesis architecture has important performance benefits over older frequency synthesizers, such as fast frequency switching, large...

Development of a CZT-Silicon Detection System in Support of the Comprehensive Nuclear-Test-Ban Treaty

Creator:: Alhawsawi, Abdulsalam M.
Abstract:: The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans all nuclear explosion tests for military or civilian purposes. The International Monitoring System (IMS) was established to verify compliance with the treaty. It consists of several monitoring stations that detect: seismic activities, hydrocoustic activities, infrasound waves, and radionuclide particles and noble gases. Radioxenon detection...

Variable sampling compensation of networked control systems with delays using neural networks

Creator:: Lopez-Echevarria, Daniel
Abstract:: In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

Scaled modeling and simulation of ocean wave linear generator buoy systems

Creator:: Gore, Ganesh P.
Abstract:: Accurate scaled modeling and simulation are critical to advancing ocean wave linear generator buoys. A 100th scaled model of ocean wave generator buoy systems is analyzed by solving the Navier-Stokes equations. These equations are numerically solved using Computational Fluid Dynamics (CFD) by implementing the front capturing method. In this thesis,...

RF and Millimeter-wave Techniques to Improve Scalability and Efficiency of Digital Beamforming Arrays

Creator:: Johnson, Manoj
Abstract:: Spectrum overcrowding, ever increasing demand for high data rate and increased mobility requirements are three major challenges 5G-technology is trying to address. In this thesis I start with a RF front-end technique that deals with blocker interference arising from spectrum overcrowding both across frequency bands and within the same frequency...

Prototyping a triple-layer phoswich detection system

Creator:: Duncan, Christopher L.
Abstract:: Multi-layer optically coupled scintillation based radiation detectors, known as phoswich detectors, have rapidly evolved in recent years. During the same time, digital signal processing has improved radiation discrimination accuracy and enhanced reliability, while reducing complexity and size of traditional analog signal processing methods. A new generation of high-speed radiation detectors...

Surface-Normal Modulation of Fano Resonances in Metallic Photonic Crystals for Free-Space Optical Interconnects

Creator:: Ren, Fanghui
Abstract:: This dissertation focuses on the development of ultra-compact optical devices for free-space modulation. We propose a surface-normal modulator using metallic photonic crystals for free-space optical interconnects. The active control of light intensity is achieved by engineering the Fano resonances in metallic photonic crystals. Both thermo-optic modulation and electro-optic modulation of...
