Kinematic and cyclostationary parameter estimation for co-channel emitter location applications

Creator:: Ohm, David R.
Abstract:: The problem of locating a signal source, or an emitter, has many civilian and military applications, such as communication regulations enforcement, military reconnaissance, and search-and-rescue operations. Many of the most widely used emitter location methods rely on the accurate and robust estimation of the differential time delay, or time-difference-of-arrival (TDOA),...

Multi-dimensional parametric estimation: two-dimensional sharpening by predictive bandwidth extrapolation and fast algorithms for three dimensional autoregressive estimation

Creator:: Liew, Ji Seok
Abstract:: Achieving sharpened (enhanced detail) features of a multi-dimensional data source using the linear prediction (LP) bandwidth extrapolation (BWE) technique in the transform domain is the main objective of this research. The evolution of sensor technology has provided acquisition scenarios in which the data format is inherently multi-dimensional, including hyperspectral imaging...

Fast algorithms and applications for multi-dimensional least-squares-based minimum variance spectral estimation

Creator:: Wei, Lin
Abstract:: The main contributions of this thesis are the development and application of four computationally efficient solutions for least-squares-based (LS-based) minimum variance spectral estimation (MVSE). They are: (1) fast computational solution for the 1-D covariance LS-based MVSE, (2) fast computational solution for the 1-D modified covariance LS-based MVSE, (3) fast computational...

Low power scheduling schemes that consider latency and resource constraints at multiple voltages

Creator:: Huang, Shyh-Sen
Abstract:: Power reduction can be achieved at many different levels, such as architecture, algorithm, logic, and transistor levels in circuit design. This thesis focuses on low power scheduling at the algorithm level. We present a latency-constrained scheduling and a latency and resource constrained scheduling, which minimize power consumption for the resources...

A multi-bit delta sigma audio digital-to-analog converter

Creator:: Wang, Ruopeng
Abstract:: Digital-to-analog converters (DACs) with wide dynamic range and high linearity are required for high-end audio applications. A multi-bit delta sigma audio DAC, using a novel gain-correction technique, is described in this thesis. For widely varying on-chip RC time constant, the DAC gain can be accurately controlled by the correction circuitry....

The stratigraphy, geochemistry, and mineralogy of two ash-flow tuffs in the Deschutes Formation, central Oregon

Creator:: Cannon, Debra May
Abstract:: Two ash-flow tuff units of the late Miocene-early Pliocene Deschute Formation in central Oregon were studied in detail because of the widespread distribution, diverse compositions, and stratigraphic importance. The Lower Bridge tuff is a double-flow simple cooling unit that is poorly welded. The upper flow grades from rhyolite in the...

Academic libraries at the center of instructional change : Faculty and librarian experience of library leadership in the transformation of teaching and learning

Creator:: Gilchrist, Debra L.
Abstract:: This phenomenological inquiry explored the experiences of library leaders and discipline faculty members engaging in a collaborative instructional change initiative focused on a process-based learning pedagogy and led by an academic library. The investigation’s purpose was providing insight and understanding concerning the: (a) library’s role in instructional leadership; (b) experience...

Performance-improving techniques for wireless systems

Creator:: Ozdural, Orhan Can
Abstract:: In this thesis, maximum likelihood Doppler frequency estimation and phase noise suppression algorithms for Orthogonal Frequency Division Multiplexing (OFDM) systems are presented. A novel handover decision algorithm for wireless systems, called predictive base station switching (PBSS), is also introduced. The maximum Doppler Frequency is the ratio of the speed of...

Pulsed ultra-wideband: transmission, detection, and performance

Creator:: Zhao, Shiwei
Abstract:: Ultra-wideband (UWB) communication has emerged as a very promising technology for short-range wireless applications, including high-speed multimedia transmissions and sensor networks. UWB system designs involve many different aspects covering analog and digital processing, channel estimation and modeling, and modulation and demodulation. Although UWB still faces many challenges, significant progress has...
