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…

This thesis studies and develops quality-of-service (QoS)-aware power allocation and frequency provisioning schemes for multicarrier wireless systems in a frequency-selective fading environment. We first develop an optimal subcarrier power allocation algorithm to maximize the energy efficiency (EE) of a single-user…

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…

Translating documents into multiple languages represents an extremely large expensefor businesses, governments, and international agencies. In Canada, for example, it isa requirement that all ocial documents exist in both ocial languages, French andEnglish. This has produced a large translation industry…

Wireless and Internet video applications are hampered by bit errors and packet errors, respectively. In addition, packet losses in best effort Internet applications limit video communication applications. Because video compression uses temporal prediction, compressed video is especially susceptible to the…

Having a complete knowledge about average traffic rates on different links in a network is highly desirable for network operators, particularly when performing tasks such as capacity planning and traffic engineering, or when making decisions on network redesigning.In this thesis,…

Specularity is a very common phenomenon in the real world and confounds many computer vision tasks such as stereo. The first purpose of this thesis is to design a real-time algorithm of specularity detection. After that, with the knowledge of…

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…

This thesis focuses on Mean Field Game (MFG) theory with applications to consensus, flocking, leader-follower and major-minor agent systems. The MFG methodology addresses a class of dynamic games with a large number of minor agents in which each agent interacts…

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…
