MAP-Based Task-Oriented Precoding for Multiuser Communication
Mohammad Javad Ahmadi, Zhentian Zhang, Rafael F. Schaefer +1
We propose a task-oriented multiuser wireless communication framework for distributed classification based on a MAP-driven system design under wireless channel impairments. \textco…
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…
Integrated Sensing and Communications for Unsourced Random Access: Fundamental Limits
Mohammad Javad Ahmadi, Rafael F. Schaefer, H. Vincent Poor
This work considers the problem of integrated sensing and communications (ISAC) with a massive number of unsourced and uncoordinated users. In the proposed model, known as the unso…
Reconfigurable Intelligent Surface Assisted MIMO Symbiotic Radio Networks
Qianqian Zhang, Ying-Chang Liang, H. Vincent Poor
In this paper, a novel reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) symbiotic radio (SR) system is proposed, in which an RIS, operating a…
