Massive MIMO technology for next generation of wireless networks
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Large scale antenna or massive multiple input multiple output (MIMO) systems are one of the key enabling technologies for fifth generation (5G) of wireless communications networks and beyond. This technology offers huge ... -
Mathematical processing of in-vivo electrophysiological data with applications to implanted electrode recordings
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Neurons are the principal cellular elements that underlie the function of the nervous system, which includes the brain, spinal cord, and peripheral ganglia. These electrically excitable cells process and transmit information ... -
Methods of signal processing applied to speech and language for objective assessment of cognitive function in ageing and psychiatry
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2014)Ageing is associated with a change in cognitive function. Impaired cognitive function is the biggest limiting factor to independence in older adults. Cognitive decline does not appear suddenly, but occurs gradually over ... -
Micro-raman investigation of si, ge and carbon related nanostructures
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2010)The degradation in performance of silicon devices with scaling caused by fundamental silicon material limitations by the year of 2020 is forcing the semiconductor industry to consider extraordinary materials to replace ... -
Microphone array processing techniques for classroom-based videoconferencing
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2008)This thesis is concerned with the design and development of microphone-array-processing techniques for videoconferencing applications in classroom environments. We argue that, in such environments, it is advantageous in ... -
Model order determination and characterisation of Direction of Arrival (DOA) estimators in the acoustic context
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2006) -
Modelling Auditory Distance Perception in Small to Medium Rooms using Binaural Room Impulse Responses
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)Auditory distance perception is fundamental to human life, necessary for spatial orientation, localization and avoidance of obstacles in environment. However, the psychoacoustics behind distance perception are quite complex, ... -
Molecular Organisation in “de Vries” Smectic Liquid Crystals: Characterisation and Theory
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2018)The study of anomalous temperature dependence of smectic layer thickness began fifty years ago. Liquid crystals exhibiting such properties were later classified as de Vries smectic liquid crystals. In this thesis I have ... -
Motion estimation reliability and the restoration of degraded archived film

Multiuser communications for next generation wireless networks
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)Orthogonal frequency division multiplexing (OFDM) has been the technology of choice for years in wired and wireless systems. However, it has some drawbacks that limit its use in the fifth generation of wireless communication ... -
Neural Turn-Taking Models for Spoken Dialogue Systems
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)In order to simulate naturalistic turn-taking behaviours, such as fast-turn switches, intentional overlap, backchanneling, and barge-in, spoken dialogue systems (SDSs) will need to have computational models of turn-taking ... -
Nonlinear response of dipolar systems to superimposed ac and dc bias fields
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2016)The main purpose of this thesis is to study the nonlinear ac stationary response of dipolar systems to superimposed ac and dc bias fields via the rotational Brownian motion model. In this way we investigate (i) the nonlinear ... -
