Reliable Extraction of Semantic Information and Rate of Innovation Estimation for Graph Signals
Mert Kalfa, Sadik Yagiz Yetim, Arda Atalik +6
Semantic signal processing and communications are poised to play a central part in developing the next generation of sensor devices and networks. A crucial component of a semantic…
Over-the-Air Federated Edge Learning with Hierarchical Clustering
Ozan Aygün, Mohammad Kazemi, Deniz Gündüz +1
We examine federated learning (FL) with over-the-air (OTA) aggregation, where mobile users (MUs) aim to reach a consensus on a global model with the help of a parameter server (PS)…
Over-the-Air Federated Learning with Energy Harvesting Devices
Ozan Aygün, Mohammad Kazemi, Deniz Gündüz +1
We consider federated edge learning (FEEL) among mobile devices that harvest the required energy from their surroundings, and share their updates with the parameter server (PS) thr…
Approximate Weight Distribution of Polarization-Adjusted Convolutional (PAC) Codes
Sadra Seyedmasoumian, Tolga M. Duman
Polarization-adjusted convolutional (PAC) codes combine the polar and convolutional transformations to enhance the distance properties of polar codes. They offer a performance very…
Unsourced Random Access with a Massive MIMO Receiver Using Multiple Stages of Orthogonal Pilots
Mohammad Javad Ahmadi, Tolga M. Duman
We study the problem of unsourced random access (URA) over Rayleigh block-fading channels with a receiver equipped with multiple antennas. We employ multiple stages of orthogonal p…
