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 ... -
Downlink Transmission in FBMC-based Massive MIMO with Co-located and Distributed Antennas
(2024)This paper introduces a practical precoding method for the downlink of Filter Bank Multicarrier-based (FBMC-based) massive multiple-input multiple-output (MIMO) systems. The proposed method comprises a two-stage precoder, ... -
The Effect of Acceleration Signal Length on the Outputs from Modal Identification Methods
(2023)The damping ratio is a significant factor influencing the dynamic behaviour of a structure. The safety, serviceability and habitability of a structure are all impacted by the damping ratio. Damping ratio does not relate ... -
Estimation of coherence using the median is robust against EEG artefacts
(2017)Coherence is a mathematical measure of correlation in the frequency domain, commonly used to quantify the oscillatory synchrony of bio-signals such as the electroencephalogram (EEG). In biomedical applications, such as ... -
A Heuristic Method for Automatic Gaze Detection in Constrained Multi-Modal Dialogue Corpora
(IEEE, 2020)We describe a heuristic-based approach to determining gaze allocation automatically in a multi-modal task oriented dialogue corpus. We present the development of the system and the evaluation of its performance and discuss ... -
Light field style transfer with local angular consistency
(2021)Style transfer involves combining the style of one image with the content of another to form a new image. Unlike traditional two-dimensional images which only capture the spatial intensity of light rays, four-dimensional ... -
Re-Engineering Rate Distortion Optimisation in Modern Video Codecs Using a Per Clip Approach
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2023)The majority of internet traffic is video content. This drives the demand for video compression to deliver high quality video at low target bitrates. Optimising the parameters of a video codec for a specific video clip ... -
RIS Meets Aerodynamic HAPS: A Multi-Objective Optimization Approach
(2023)In this letter, we propose a novel network architecture for integrating terrestrial and non-terrestrial networks (NTNs) to establish connection between terrestrial ground stations which are unconnected due to blockage. ... -
Time and Frequency Synchronization for OTFS
(2022)In this letter, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads ...
