Scalable Cell-Free Massive MIMO Unsourced Random Access System
Michail Gkagkos, Jean-Francois Chamberland, Costas N. Georghiades +1
Cell-Free Massive MIMO systems aim to expand the coverage area of wireless networks by replacing a single high-performance Access Point (AP) with multiple small, distributed APs co…
PolarAir: A Compressed Sensing Scheme for Over-the-Air Federated Learning
Michail Gkagkos, Krishna R. Narayanan, Jean-Francois Chamberland +1
We explore a scheme that enables the training of a deep neural network in a Federated Learning configuration over an additive white Gaussian noise channel. The goal is to create a…
FASURA: A Scheme for Quasi-Static Massive MIMO Unsourced Random Access Channels
Michail Gkagkos, Krishna R. Narayanan, Jean-Francois Chamberland +1
This article considers the massive MIMO unsourced random access problem on a quasi-static Rayleigh fading channel. Given a fixed message length and a prescribed number of channel u…
Approximate Support Recovery using Codes for Unsourced Multiple Access
Michail Gkagkos, Asit Kumar Pradhan, Vamsi Amalladinne +3
We consider the approximate support recovery (ASR) task of inferring the support of a -sparse vector from noisy measurements. We examine the case…
Asymptotic Performance Analysis of Generalized User Selection for Interference-Limited Multiuser Secondary Networks
Yazan H. Al-Badarneh, Costas N. Georghiades, Mohamed-Slim Alouini
We analyze the asymptotic performance of a generalized multiuser diversity scheme for an interference-limited secondary multiuser network of underlay cognitive radio systems. Assum…
On the Secrecy Performance of Generalized User Selection for Interference-Limited Multiuser Wireless Networks
Yazan H. Al-Badarneh, Costas N. Georghiades, Redha M. Radaydeh +1
We investigate the secrecy performance of a multiuser diversity scheme for an interference-limited wireless network with a base-station (BS), legitimate users and an eavesdropp…
