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…
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…
A General Sensing-assisted Channel Estimation Framework in Distributed MIMO Network
Hui Zhou, Xiaolan Liu, Sangarapillai Lambotharan
In 6G communications, it is envisioned to equip the traditional access point (AP) with sensing capability to fully benefit the existing wireless communication infrastructures. Thus…
