Reconfigurable OFDM systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier wireless transmission technique. OFDM is used for robust, high quality and high data-rate music, voice, images, video, news and data broadcasts. It is ... -
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 ... -
Spectroscopic investigations of SiGe nano-structures
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)This work investigates the growth of several novel structures using a variety of spectroscopic techniques. Strained Si caps deposited on a relaxed SiGe layer are grown with resulting dislocations found to be perfectly ... -
The frequency and field dependence of magnetic colloidal suspensions
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)This thesis is a study of the dynamic magnetisation of various magnetic fluids, commonly known as ferrofluids. The fluids contain either magnetic nanoparticles, or magnetic microspheres. The method used to study the magnetization ... -
Ad hoc key management
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2006)This dissertation analyses the problem of providing Key Management Infrastructure (KMI) in an ad hoc network. A novel solution is proposed designed and implemented that facilitates both types of KMI that are deployed in ... -
Flexibility in ad hoc networks
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)This thesis represents a step forward in our understanding of what flexibility, adaptability and reconfigurability means at the network-layer of mobile, wireless, ad hoc networks. Mobile, wireless, ad hoc networks are ... -
Optimum stability in control system design
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)This thesis develops for the first time a general approach to the design of control systems that emphasizes optimum system stability as the primary design criterion. The design method is to select controller parameters ... -
Culture of Spectrum Sharing: Emancipation of the hertz
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2019)Increase on demands for lower latency, pervasive connectivity, higher throughput, and more capacity has an exponential trend. To meet the demands is to put to use all spectrum resources we have and all of the technology ... -
On the Performance and Design Tradeoffs of Low Altitude UAV Small Cells in Urban Environments
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2019)Cellular data demand continues to increase from year to year, and to manage this rising demand network operators adopt new technologies and designs for their cellular networks. Among these, network densification is seen ... -
Towards a greater understanding of the neurophysiology of natural audiovisual speech processing : a system identification approach to EEG
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2016)Seeing a speaker’s face as he or she talks can greatly help in understanding what the speaker is saying, especially in adverse hearing conditions – a principle known as inverse effectiveness. This is because the speaker’s ... -
Algorithmic level low-power VLSI design applied to RGB to HSI conversion
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2001)The growing demand for portable applications such as cellular phones, portable digital assistants (PDAs) and notebooks has resulted in a requirement for integrated circuits (ICs) which consume less power while delivering ... -
Application of capacitive sensors to inverse problems in electrostatics
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2003)The electrostatic imaging problem is an inverse electrostatic problem Involving the reconstruction of an inhomogeneous dielectric medium from a set of remote electrostatic field measurements. In this thesis we propose ... -
Enabling coalitions between Independent Networks
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)The ways in which networks are built, owned and controlled have evolved in recent years. The traditional model, of a single entity owning or somehow participating in the entire telecommunications value chain, has begun to ... -
Spectre of the commons : a political economy of radio regulation in the communism of capital
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2014)This thesis performs a critique of the political economy of mobile networks through the theoretical framework of the communism of capital. It identifies the economic centrality of social production to the contemporary ... -
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 ... -
