Transceiver Design for Cell-Free Unsourced Random Access
Mert Ozates, Mohammad Kazemi, Eduard Jorswieck +1
We propose a low-complexity, energy-efficient solution for cell-free unsourced random access (URA), in which multiple distributed access points are connected to a central processin…
Cluster-Aware Over-the-Air Federated Learning with Energy-Harvesting Devices: From Global Training to Model Personalization
Furkan Bagci, Busra Tegin, Mohammad Kazemi +1
Federated learning (FL) enables distributed optimization and learning across decentralized edge devices while preserving data privacy, but its performance is fundamentally constrai…
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…
Learned Digital Over-the-Air Computing for Federated Edge Learning
Antonio Tarizzo, Mohammad Kazemi, Deniz Gündüz
Over-the-air (OTA) aggregation enables federated edge learning (FEEL) by exploiting the superposition property of the wireless channel to merge communication with computation, elim…
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.…
