Application of Compressive Sensing to Weather Radars
(2016-12-16)
The capability and importance of weather radar are proven for hazardous weathers detection, monitoring, and prediction in both research and operations. Continuous efforts have been made in improving radar performance in ...
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 ...
Channel detection on two-dimensional magnetic recording
(2013)
Two-dimensional magnetic recording (TDMR) coupled with shingled-magnetic recording (SMR) is one of next generation techniques for increasing the hard disk drive (HDD) capacity up to 10 Tbit/in2 in order to meet the growing ...
ADVANCED SIGNAL PROCESSING FOR MAGNETIC RECORDING ON PERPENDICULARLY MAGNETIZED MEDIA
(2010)
In magnetic recording channels (MRCs) the readback signal is corrupted by many kinds of impairments, such as electronic noise, media noise, intersymbol interference (ISI), inter-track interference (ITI) and different types ...
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 ...
WAVEFORM AND TRANSCEIVER OPTIMIZATION FOR MULTI-FUNCTIONAL AIRBORNE RADAR THROUGH ADAPTIVE PROCESSING
(2013)
Pulse compression techniques have been widely used for target detection and remote sensing. The primary concern for pulse compression is the sidelobe interference. Waveform design is an important method to improve the ...
ADAPTIVE AND SECURE DISTRIBUTED SOURCE CODING FOR VIDEO AND IMAGE COMPRESSION
(2013)
Distributed Video Coding (DVC) is rapidly gaining popularity as a low cost, robust video coding solution, that reduces video encoding complexity. DVC is built on Distributed Source Coding (DSC) principles where correlation ...
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 ...
Problems in the design and operation of uncertain complex engineering systems
(2011)
In this dissertation, we consider two problems. The first one is a general approach to the optimal design of uncertain dynamical systems, where the uncertainty is represented by a random parameter. The problem is formulated ...
Self-Packaged and Low-Loss Suspended Integrated Stripline Filters for Next Generation Systems
(2018-08-02)
The method in which the frequency spectrum is currently allocated is unsustainable. An increasing number of devices are becoming wireless, overcrowding an already crowded spectrum (e.g., the ISM band). Therefore, future ...
