Pseudo-Noise Superposition for Finite-Alphabet Physical Layer Security
Fernando Moya Caceres, Chamath Divarathne, Yapeng Xie +4
Physical-layer security based on pseudo-noise (PN) superposition is a promising approach for mitigating eavesdropping in future wireless systems. However, under Shannon's capacity…
Null-Shaping for Interference Mitigation in LEO Satellites Under Location Uncertainty
Fernando Moya Caceres, Akram Al-Hourani, Saman Atapattu +1
Radio frequency interference (RFI) poses a growing challenge to satellite communications, particularly in uplink channels of Low Earth Orbit (LEO) systems, due to increasing spectr…
Eigenvalue-Based Detection in MIMO Systems for Integrated Sensing and Communication
Alex Obando, Saman Atapattu, Prathapasinghe Dharmawansa +2
This paper considers a MIMO Integrated Sensing and Communication (ISAC) system, where a base station simultaneously serves a MIMO communication user and a remote MIMO sensing recei…
Interference Mitigation in LEO Constellations with Limited Radio Environment Information
Fernando Moya Caceres, Akram Al-Hourani, Saman Atapattu +8
This research paper delves into interference mitigation within Low Earth Orbit (LEO) satellite constellations, particularly when operating under constraints of limited radio enviro…
Deep Learning Methods for Device Identification Using Symbols Trace Plot
Da Huang, Akram Al-Hourani, Kandeepan Sithamparanathan +1
Devices authentication is one crucial aspect of any communication system. Recently, the physical layer approach radio frequency (RF) fingerprinting has gained increased interest as…
