In the last few decades, the world of electric machine design, specifically induction machine design, has been reinvigorated by the introduction of power electronics. Where designers were once limited to a single alternating current waveform with constant voltage and frequency,…

Distributed estimation in a wireless sensor network has many advantages. It eliminates the need of the centralized knowledge of the measurement model parameters and does not have a single point of failure. Also, any sensor node can be queried to…

During a forensic interview, high-stakes deception is very prevalent notwithstanding the heavy consequences that may result. Studies have shown that most untrained people cannot perform well in discerning liars and truth-tellers. Thus it has become common to adopt various technical…

Ultra Wideband (UWB) Impulse Radio (IR) technology has attracted considerable attention in the past few years due to its many desirable properties, such as the ability to penetrate through walls and ground, low power spectral density level, immunity to multipath…

Low-Density Parity-Check (LDPC) codes are one of the most powerful classes of error-control codes known to date. These codes have been considered for many recent digital communication applications. In this dissertation, we propose stochastic decoding of state-of-the-art LDPC codes and…

This thesis presents a theoretical and experimental study of the nonlinear behaviour of analog synthesizers' effects. The goal of this thesis is to evaluate and complete current research on nonlinear system modelling, both in and out of the field of…

Energy detection has emerged as a prime technique for wideband spectrum sensing in cognitive radio applications. Much of the present research in the area of energy detection assumes that the occupancy of any particular frequency subband is independent of the…

In this thesis we present two integrated solutions suitable for measuring the timing jitter of digital signals in SoCs and data acquisition systems (mainly sampling ADCs). The presented methods are also suitable for time measurement in a variety of timing-based…

This thesis presents a study of optimal threshold designs for energy-detection based spectrum sensing in a cognitive-radio network with a pair of Primary-User (PU) transmitter-receiver and a pair of Secondary-User (SU) transmitter-receiver uniformly distributed in their corresponding transmission and interference…
