Deep Tech to Space: Space Data Centers and AI Revolution at the Edge
Jonas Weiss, Patricia Sagmeister, Gabriel Maiolini Capez +16
Dramatic cost reductions driven by private sector innovations have led to a rapid increase in the number of satellites in orbit and a corresponding surge in space-generated data. A…
Secrecy Energy Efficiency Maximization in RIS-Aided Networks: Active or Nearly-Passive RIS?
Robert Kuku Fotock, Agbotiname Lucky Imoize, Alessio Zappone +2
This work addresses the problem of secrecy energy efficiency (SEE) maximization in RIS-aided wireless networks. The use of active and nearly-passive RISs are compared and their tra…
Secrecy Energy Efficiency Maximization in RIS-Aided Wireless Networks with Statistical CSI
Robert Kuku Fotock, Agbotiname Lucky Imoize, Alessio Zappone +2
This work studies the problem of secrecy energy efficiency maximization in multi-user wireless networks aided by reconfigurable intelligent surfaces, in which an eavesdropper overh…
Design and Performance of Enhanced Spread Spectrum Aloha for Unsourced Multiple Access
Riccardo Schiavone, Gianluigi Liva, Roberto Garello
We analyze the performance of enhanced spread spectrum Aloha (E-SSA) in the framework of unsourced multiple access (UMAC). The asynchronous, unframed transmission of E-SSA is modif…
