Secret-key-based physical layer security for feedback-aided unsourced random access
Mohammad Javad Ahmadi, Rafael F. Schaefer, F. Rostami Ghadi +1
This work introduces security for unsourced random access (URA) via a physical-layer security approach. To achieve confidentiality, the proposed system opportunistically exploits i…
Efficient Feedback Design for Unsourced Random Access with Integrated Sensing and Communication
Mohammad Javad Ahmadi, Mohammad Kazemi, Rafael F. Schaefer
We consider an unsourced random access (URA) system enhanced with a feedback mechanism that serves both communication and sensing tasks. While traditional URA systems do not incorp…
Sparse Code Transceiver Design for Unsourced Random Access with Analytical Power Division in Gaussian MAC
Zhentian Zhang, Mohammad Javad Ahmadi, Jian Dang +3
In this work, we discuss the problem of unsourced random access (URA) over a Gaussian multiple access channel (GMAC). To address the challenges posed by emerging massive machine-ty…
