When Robots Exchange Meaning: A Demo of Goal-Oriented Semantic Communications for Collaborative Robotics
Peizheng Li, Xinyi Lin, Sajida Gufran +1
The paper demonstrates a robot‑edge semantic communication testbed that compresses visual data into VQ‑VAE tokens on a mobile robot and reconstructs it on an edge device for semant…
The Price of Meaning: Quantifying Semantic Communication Overheads in Practice
Xinyi Lin, Peizheng Li, Adnan Aijaz
The paper presents an analytical framework to quantify the spectral and energy overheads of semantic communication, identifying conditions under which semantic compression yields n…
Latency-aware Human-in-the-Loop Reinforcement Learning for Semantic Communications
Peizheng Li, Xinyi Lin, Adnan Aijaz
Semantic communication promises task-aligned transmission but must reconcile semantic fidelity with stringent latency guarantees in immersive and safety-critical services. This pap…
Satellite Direct-to-Device from Low Earth Orbit: Techno-Economic Analysis of a Global Non-Terrestrial Network
Adnan Aijaz, Peizheng Li, Sajida Gufran
Low Earth orbit (LEO) satellites and satellite direct-to-device (D2D) technology are at the heart of the next-generation global connectivity which promises direct access to space-b…
Building the Self-Improvement Loop: Error Detection and Correction in Goal-Oriented Semantic Communications
Peizheng Li, Xinyi Lin, Adnan Aijaz
Error detection and correction are essential for ensuring robust and reliable operation in modern communication systems, particularly in complex transmission environments. However,…
Flying Base Stations for Offshore Wind Farm Monitoring and Control: Holistic Performance Evaluation and Optimization
Xinyi Lin, Peizheng Li, Adnan Aijaz
Ensuring reliable and low-latency communication in offshore wind farms is critical for efficient monitoring and control, yet remains challenging due to the harsh environment and la…
