An Age of Information Characterization of SPS
Maria Bezmenov, Matthias Frey, Zoran Utkovski +1
We derive a closed-form approximation of the stationary distribution of the Age of Information (AoI) of the semi-persistent scheduling (SPS) protocol which is a core part of NR-V2X…
Simultaneous Computation and Communication over MAC
Matthias Frey, Igor Bjelaković, Michael C. Gastpar +1
We study communication over a Gaussian multiple-access channel (MAC) with two types of transmitters: Digital transmitters hold a message from a discrete set that needs to be commun…
Inverse Feasibility in Over-the-Air Federated Learning
Tomasz Piotrowski, Rafail Ismayilov, Matthias Frey +1
We introduce the concept of inverse feasibility for linear forward models as a tool to enhance OTA FL algorithms. Inverse feasibility is defined as an upper bound on the condition…
A Learning-Based Approach to Approximate Coded Computation
Navneet Agrawal, Yuqin Qiu, Matthias Frey +4
Lagrange coded computation (LCC) is essential to solving problems about matrix polynomials in a coded distributed fashion; nevertheless, it can only solve the problems that are rep…
Semantic Security with Infinite Dimensional Quantum Eavesdropping Channel
Matthias Frey, Igor Bjelaković, Janis Nötzel +1
We propose a new proof method for direct coding theorems for wiretap channels where the eavesdropper has access to a quantum version of the transmitted signal on an infinite-dimens…
Over-The-Air Computation in Correlated Channels
Matthias Frey, Igor Bjelakovic, Slawomir Stanczak
This paper addresses the problem of Over-The-Air (OTA) computation in wireless networks which has the potential to realize huge efficiency gains for instance in training of distrib…
