Localization Attack by Precoder Feedback Overhearing in 5G Networks and Countermeasures
Stefan Roth, Stefano Tomasin, Marco Maso +1
In fifth-generation (5G) cellular networks, users feed back to the base station the index of the precoder (from a codebook) to be used for downlink transmission. The precoder is st…
Remote Short Blocklength Process Monitoring: Trade-off Between Resolution and Data Freshness
Stefan Roth, Ahmed Arafa, H. Vincent Poor +1
In cyber-physical systems, as in 5G and beyond, multiple physical processes require timely online monitoring at a remote device. There, the received information is used to estimate…
Base-Stations Up in the Air: Multi-UAV Trajectory Control for Min-Rate Maximization in Uplink C-RAN
Stefan Roth, Ali Kariminezhad, Aydin Sezgin
In this paper we study the impact of unmanned aerial vehicles (UAVs) trajectories on terrestrial users' spectral efficiency (SE). Assuming a strong line of sight path to the users,…
On The Efficiency of Widely Linear Precoding and Symbol Extension in Cellular Uplink
Ali Kariminezhad, Stefan Roth, Aydin Sezgin +1
We investigate Gaussian widely linear precoding known as improper Gaussian signaling for the cellular uplink with inter-cell interference, known as interference multiple access cha…
