Low-Complexity Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Low-Complexity Reliability-Based Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Joint Channel Estimation and Equalization in Massive MIMO Using a Single Pilot Subcarrier
(2023)The focus of this letter is on the reduction of the large pilot overhead in orthogonal frequency division multi-plexing (OFDM) based massive multiple-input multiple-output (MIMO) systems. We propose a novel joint channel ... -
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 ... -
Whole-body sodium-mri at 3 T using an asymmetric birdcage resonator and short echo time sequence: first images of a male volunteer
(2012)Sodium magnetic resonance imaging (²³Na MRI) is a non-invasive technique which allows spatial resolution of the tissue sodium concentration (TSC) in the human body. TSC measurements could potentially serve to monitor early ... -
Bilateral 23Na MR imaging of the breast and quantification of sodium concentration
(2014)A novel setup for 23 Na MRI, which allows bilateral imaging of the breast, is presented. For this purpose a figure- eight receive-only 23 Na surface coil was developed. For our experiments on three samples with NaCl ... -
The localization of focal heart activity via body surface potential measurements: tests in a heterogeneous torso phantom
(2009)The non-invasive localization of focal heart activity via body surface potential measurements (BSPM) could greatly benefit the understanding and treatment of arrhythmic heart diseases. However, the in vivo validation of ... -
Sodium-23 magnetic resonance imaging during and after transient cerebral ischemia: multinuclear stroke protocols for double-tuned (23)Na/(1)H resonator systems
(2012)A double-tuned 23Na/1H resonator system was developed to record multinuclear MR image data during and after transient cerebral ischemia. 1H-diffusion-, 1H perfusion, 1H T2-, 1H arterial blood flow- and 23Na spin density-weighted ... -
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, ... -
Truncated Turbo Equalizer with SIC for OTFS
(2023)Orthogonal time frequency space (OTFS) is a promising candidate waveform for the next generation wireless communication systems. OTFS places data in the delay-Doppler (DD) domain, which simplifies channel estimation in ... -
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. ... -
Few-Shot Learning and Learnable Frontends for Remote Monitoring of Bird Populations
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2024)In response to changing ecological and environmental factors, automated monitoring of bird populations has become imperative for conservation efforts and as an indicator of change in its own right. This is particularly ... -
Signal-to-noise ratio of a mouse brain (13) C CryoProbe system in comparison with room temperature coils: spectroscopic phantom and in vivo results.
(2014)MRI and MRS in small rodents demand very high sensitivity. Cryogenic transmit/receive radiofrequency probes (CryoProbes) designed for (1) H MRI of mouse brain provide an attractive option for increasing the performance of ... -
Segmental evaluation of Text-to-Speech synthesis
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2024)Advancements in speech synthesis technology have mandated the need for reliable methods for its evaluation. Present day evaluation, dominated by subjective listening tests, provides at best, a general overall picture of ... -
Bone length calibration can significantly improve the measurement accuracy of knee flexion angle when using a marker-less system to capture the motion of countermovement jump
(2016)Marker-less motion capture systems can provide online recordings of human biomechanics during rapid dynamic exercises such as countermovement jump (CMJ) which could indicate an athlete's risk of injury to the anterior ... -
Compact Beamforming Antennas for IoT-Enabled Directional Modulation and Localization
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2024)In recent years, there has been a considerable focus in various research domains directed towards the miniaturization of wireless communication devices. This increasing demand for highly compact systems is a growing trend ... -
MONITORING OF VOLUME STATUS USING A NOVEL SENSOR FOR THE ASSESSMENT OF INFERIOR VENA CAVA AREA AND COLLAPSIBILITY IN A PATIENT WITH HFREF RECEIVING ADVANCED HEART FAILURE THERAPIES
(2023)Background: A novel sensor designed to measure infe- rior vena cava (IVC) area over time was used in this study (FIRE1). The system consists of the implantable sensor and an external belt, which is worn around the ... -
IN SILICO MODELLING OF FLOW-INDUCED COLLAPSE OF BLOOD VESSELS: A COMPARATIVE STUDY OF VOLUME STATUSES
