ViSQOLAudio: An objective audio quality metric for low bitrate codecs
(2015)Streaming services seek to optimise their use of bandwidthacross audio and visual channels to maximise the quality of experiencefor users. This letter evaluates whether objective quality metrics can pre-dict the audio ... -
Objective Assessment of Perceptual Audio Quality Using ViSQOLAudio
(2017)Digital audio broadcasting services transmit substantial amounts of data that is encoded to minimize bandwidth whilst maximizing user quality of experience. Many large service providers continually alter codecs to improve ... -
Active Damping of Power Oscillations Following Frequency Changes in Low Inertia Power Systems
(2019)The absolute requirement to increase the amount of energy generation from renewable sources e.g. predominantly asynchronously connected wind turbines and photovoltaic installations, may in practice during transient events ... -
Expansion and phase correlation of a wavelength tunable gain-switched optical frequency comb
(2019)A novel scheme for the expansion and phase correlation of a wavelength tunable gain-switched optical frequency comb (OFC) is presented. This method entails firstly combining two gain-switched ... -
Efficient encoding and decoding of binaural sound with resonance audio
(2019)Resonance Audio is an open source project designed for creating and controlling dynamic spatial sound in Virtual & Augmented Reality (VR/AR), gaming or video experiences. It also provides integrations with popular game ... -
Performance of Massive MIMO Self-Backhauling for Ultra-Dense Small Cell Deployments

Cooperative Transmission and Probabilistic Caching for Clustered D2D Networks
(2019)In this paper, we aim at maximizing the cache off loading gain for a clustered device-to-device (D2D) caching network by exploiting probabilistic caching and cooperative transmission among the ... -
Towards predicting dialog acts from previous speakers' non-verbal cues
(2017)In studies of response times during conversational turn-taking, a modal time of 200 ms has been observed to be a universal value that exists across languages and cross-culturally. This 200 ms value is also seen as the limit ... -
Characterising the Human Auditory System using a Linear Least-Squares System Identification Approach
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2019)Disabling hearing loss affects many millions of people around the world.Early identification and suitable interventions, e.g., the provision of hearing aids, cochlear implants, etc., can help but are limited ... -
The variational Bayes approach in signal processing
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2004)This thesis is concerned with Bayesian identification of parameters of linear models.
