Beamforming and RIS-Aided Ambient Backscatter Communications with Residual-Feature SVM Detection
Aobakwe Makgarapa, Burhan Wafai, Sangarapillai Lambotharan +1
Ambient backscatter communication (AmBC) enables battery-free connectivity by modulating data onto existing radio-frequency (RF) signals, eliminating the need for dedicated power s…
LLM-Enhanced Space-Air-Ground-Sea Integrated Networks
Halvin Yang, Sangarapillai Lambotharan, Mahsa Derakhshani +1
The space-air-ground-sea integrated networking (SAGSIN) concept promises seamless global multimedia connectivity, yet two obstacles still limit its practical deployment. Firstly, h…
FAS-LLM: Large Language Model-Based Channel Prediction for OTFS-Enabled Satellite-FAS Links
Halvin Yang, Sangarapillai Lambotharan, Mahsa Derakhshani
This paper proposes FAS-LLM, a novel large language model (LLM)-based architecture for predicting future channel states in Orthogonal Time Frequency Space (OTFS)-enabled satellite…
Performance Analysis of Fluid Antenna System Aided OTFS Satellite Communications
Halvin Yang, Mahsa Derakhshani, Sangarapillai Lambotharan +1
Internet-of-Things (IoT) networks typically rely on satellite communications to provide coverage in rural areas. However, high-mobility satellite links introduce severe Doppler and…
Joint Attention Mechanism Learning to Facilitate Opto-physiological Monitoring during Physical Activity
Xiaoyu Zheng, Sijung Hu, Vincent Dwyer +2
Opto-physiological monitoring including photoplethysmography (PPG) provides non-invasive cardiac and respiratory measurements, yet motion artefacts (MAs) during physical activity d…
Reinforcement Learning-Based Downlink Transmit Precoding for Mitigating the Impact of Delayed CSI in Satellite Systems
Yasaman Omid, Marios Aristodemou, Sangarapillai Lambotharan +2
The integration of low earth orbit (LEO) satellites with terrestrial communication networks holds the promise of seamless global connectivity. The efficiency of this connection, ho…
Tackling Delayed CSI in a Distributed Multi-Satellite MIMO Communication System
Yasaman Omid, Sangarapillai Lambotharan, Mahsa Derakhshani
In this study, we explore the integration of satellites with ground-based communication networks. Specifically, we analyze downlink data transmission from a constellation of satell…
Dynamic Non-Orthogonal Multiple Access (NOMA) and Orthogonal Multiple Access (OMA) in 5G Wireless Networks
Mina Baghani, Saeedeh Parsaeefard, Mahsa Derakhshani +1
In this paper, facilitated via the flexible software defined structure of the radio access units in 5G, we propose a novel dynamic multiple access technology selection among orthog…
