COGNITIVE MULTI-USER FREE SPACE OPTICAL COMMUNICATION
(2020-11-11)
Increasing deployment of terrestrial, aerial, and space-based assets designed with more demanding services and applications is dramatically escalating the need for high capacity, high data-rate, adaptive, and flexible ...
DETECTION THRESHOLDS FOR SPECTRAL MOMENTS AND POLARIMETRIC VARIABLES
(2008)
Presently, the Signal-to-Noise-Ratio (SNR) measurement is used to determine the presence of a weather signal for Weather Surveillance Radar - 1988 Doppler (WSR-88D). Growing popularity of polarimetric radars prompts the ...
A formalism for the syntactic description and recognition of two dimensional patterns /
(1981)
The concept of imaginary parsing is advanced for recognition of partially obscured patterns.
The Atmospheric Imaging Radar for High Resolution Observations of Severe Weather
(2012)
Mobile weather radars often utilize rapid scan strategies when collecting obser- vations of severe weather. Various techniques have been used to improve volume update times, including the use of agile and multi-beam radars. ...
Distributed Computation of Graph Spectrum, Eigenvector Centrality, and Solution to Linear Equations
(2017-12-15)
This dissertation is devoted to the development of distributed algorithms, with which nodes in a large decentralized network can accomplish tasks that are seemingly difficult without an omniscient central node. The tasks ...
Real-Time Narrowband and Wideband Beamforming Techniques for Fully-Digital RF Arrays
(2017-12)
Elemental digital beamforming offers increased flexibility for multi-function radio frequency (RF) systems supporting radar and communications applications. As fully digital arrays, components, and subsystems are becoming ...
Robust Optical Wireless Links over Turbulent Media using Diversity Solutions
(2011)
Free-space optic (FSO) technology, i.e., optical wireless communication (OWC), is widely recognized as superior to radio frequency (RF) in many aspects. Visible and invisible optical wireless links solve first/last mile ...
WAAS error, integrity and availability modeling for GPS based aircraft landing system.
(2004)
From its initial conception to deployment, the Wide Area Augmentation System (WAAS) was hailed as revolutionary for the navigation industry. However, the WAAS deployment effort has suffered significant delays and budget ...
QUANTUM SECURE COMMUNICATION USING POLARIZATION HOPPING MULTI-STAGE PROTOCOLS
(2016)
This dissertation presents a study of the security and performance of a quantum communication system using multi-stage multi-photon tolerant protocols. Multi-stage protocols are a generalization of the three-stage protocol ...
