Detection of Signals in Colored Noise: Roy's Largest Root Test for Non-central -matrices
Prathapasinghe Dharmawansa, Saman Atapattu, Jamie Evans +1
This paper investigates the signal detection problem in colored noise with an unknown covariance matrix. In particular, we focus on detecting a non-random signal by capitalizing on…
Standard Condition Number-Based Robust Signal Detection with Whitening under Uncertainty
Tharindu Udupitiya, Saman Atapattu, Prathapasinghe Dharmawansa +2
Robust signal detection in colored noise with unknown covariance is essential in radar, cognitive radio, integrated sensing and communication (ISAC), and quantum sensing applicatio…
Graph Neural Networks for Physical-Layer Security in Multi-User Flexible-Duplex Networks
Tharaka Perera, Saman Atapattu, Yuting Fang +1
This paper explores Physical-Layer Security (PLS) in Flexible Duplex (FlexD) networks, considering scenarios involving eavesdroppers. Our investigation revolves around the intricac…
