Improved nonlinear filtering for target tracking.
(2007)
The objective of this research is to develop robust and accurate tracking algorithms for various tracking applications. These tracking problems can be formulated as nonlinear filtering problems. The tracking algorithms ...
Mid-infrared emitter technology.
(2006)
As part of an effort to improve heat dissipation from mid-infrared laser materials during operation, work was performed on mounting laser bars in an epi-side-down configuration. Results obtained from packaging interband ...
Estimation of Doppler and polarimetric variables for weather radars.
(2001)
A method for estimation of Doppler spectrum and its moments as well as several polarimetric variables on pulsed weather radars is presented. This scheme operates on oversampled echoes in range, that is samples of in-phase ...
A study on mobile ad hoc networks equipped with free-space optical capabilities.
(2006)
A mobile ad hoc network (MANET) offers a cost-effective solution for communications in areas where infrastructure is unavailable, e.g. emergency response, disaster recovery, and battlefield scenarios. Traditional MANETs ...
Performance evaluation of CDMA systems.
(2001)
Also, various coding techniques are compared for the forward link of IS-2000 systems in this dissertation. The possible application of low-density parity-check (LDPC) coding in CDMA systems is investigated. Its performance ...
MBE GROWTH AND CHARACTERIZATION OF Pb-SALT SEMICONDUCTORS FOR MID-INFRARED DETECTOR AND LASER APPLICATION
(2009)
IV-VI semiconductors grown by molecular beam epitaxy (MBE) on various substrates are extensively attractive for mid-infrared optoelectronic device application. The main goal of this research is to improve device performance ...
Digital signal processing on the unit sphere via a Ramanujan set of rotations and planar wavelets.
(2000)
We give a sufficient condition for a zonal function to be a strictly positive definite. A major result of this thesis is that we have proven Shreiner's result as a consequence of a more general representation-theoretic ...
Error-correction coding for high-density magnetic recording channels.
(2004)
Finally, a promising algorithm which combines RS decoding algorithm with LDPC decoding algorithm together is investigated, and a reduced-complexity modification has been proposed, which not only improves the decoding ...
IDENTIFICATION AND ESTIMATION OF MULTI-MODAL COMPLEX DYNAMIC SYSTEM
(2009)
In this dissertation we study identification of complex dynamic systems as well as hybrid system estimation. For the identification part, we propose a scheme to identify an autonomous complex stochastic dynamic system based ...
Multiplierless CSD techniques for high performance FPGA implementation of digital filters.
(2007)
I leverage FastCSD to develop a new, high performance iterative multiplierless structure based on a novel real-time CSD recoding, so that more zero partial products are introduced. Up to 66.7% zero partial products occur ...
