Non-data aided parametric based carrier frequency estimators for bursty GMSK communication systems

Creator:: Kandukuri, Ajay
Abstract:: Estimating the carrier frequency from a modulated waveform is one of the most important functions of a coherent signal receiver. Good performance and low bit error rates are obtained by coherent demodulation. Therefore, exact knowledge of the received signal carrier frequency is critical for communication systems. Also due to the...

Evaluation of UWB techniques for indoor position locationing

Creator:: Chou, Tai Chian
Abstract:: Time of Arrival (TOA) is a popular technique used for geolocation. This thesis evaluates the use of TOA techniques indoors. The accuracy of measuring distances using TOA is dependent on the bandwidth of the system and the multipath conditions between the receiver and transmitter. System bandwidth has a significant effect...

Hybrid electric vehicle dc-bus converter harmonics

Creator:: Mills-Price, Michael A.
Abstract:: As more advanced hybrid electric vehicles begin emerging onto the commercial market, design algorithms for their control become increasingly more complicated. One major hurdle for designers is the mitigation and control of the created high frequency harmonics caused from switching the dc voltage into an ac voltage by use of...

Comparison and analysis of jitter in CMOS ring oscillators

Creator:: Natesan, Peroly
Abstract:: A comparison and analysis of jitter for five different architectures of ring oscillators using a novel simulation technique developed by Professor Forbes' group is presented. Ring oscillators have become an essential building block in many digital and synchronous communications system due to their integrated nature and are widely used in...

Multiple antenna techniques for pulse-based ultra-wideband system

Creator:: Vemulapalli, Sudheer
Abstract:: fIndoor wireless local area networks (LAN's) and personal area networks (PAN’s) have evolved very rapidly in the recent past. The indoor wireless LAN's are mainly dominated by narrow-band technologies like the IEEE 802.11a,b which are short range and provide data rates of 1 Mbps to 54 Mbps. The Bluetooth has...

Hybrid electric vehicle converter harmonics

Creator:: Bowers, Waylon T.
Abstract:: Hybrid electric vehicles (HEV’s) are a very important part of today’s transportation system as they are bridging the gap between fully electric vehicles and conventional internal combustion vehicles (ICV’s). They have much higher efficiencies and lower emissions than ICV’s, while still having the ability to travel long range and refuel...

Investigation and comparison of generators for dynamic operation in ocean buoys

Creator:: Schacher, Anthony Clinton
Abstract:: A significantly untapped renewable energy source exists in the world's oceans. It is estimated that if 0.2% of the ocean's untapped energy could be harnessed, it could provide power sufficient for the entire world. Ocean energy extraction is an old concept, and it is currently seeing the benefit of advancing...

Novel control of a permanent magnet linear generator for ocean wave energy applications

Creator:: VanderMeulen, Aaron H.
Abstract:: Wave energy conversion devices are a rapidly growing interest worldwide for the potential to harness a sustainable and renewable energy source. Due to the oscillatory nature of ocean waves, the power generated from a permanent magnet linear generator (PMLG) for ocean wave energy conversion is pulsed. Focusing on direct drive...

A linear test bed for characterizing the performance of ocean wave energy converters

Creator:: Hogan, Peter M.
Abstract:: Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

Hybrid electric vehicle active rectifier performance analysis

Creator:: Amon, Ean A.
Abstract:: In advanced hybrid electric vehicle development, performance and dependability are essential considerations in the design process. High efficiency is crucial in a successful design and fault tolerance is necessary to provide limp-home capability under faulted operating conditions. The reduction of electromagnetic interference is mandatory to reduce interference in communications and...
