Fully Asynchronous Unsourced Random Access over Fading Channels
Mert Ozates, Mohammad Kazemi, Gianluigi Liva +1
We examine unsourced random access in a fully asynchronous setup, where active users transmit their data without restriction on the start time over a fading channel. In the propose…
Unsourced Random Access: A Comprehensive Survey
Mert Ozates, Mohammad Javad Ahmadi, Mohammad Kazemi +2
Multiple access communication systems enable numerous users to share common communication resources, playing a crucial role in wireless networks. With the emergence of the sixth ge…
Communication via Sensing
Mohammad Kazemi, Tolga M. Duman, Deniz Gündüz
We present an alternative take on the recently popularized concept of `\textit{joint sensing and communications}', which focuses on using communication resources also for sensing.…
Characterization of Deletion/Substitution Channel Capacity for Small Deletion and Substitution Probabilities
Mohammad Kazemi, Tolga M. Duman
We consider binary input deletion/substitution channels, which model certain types of synchronization errors encountered in practice. Specifically, we focus on the regime of small…
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…
