Enhancing Physical Layer Security for NOMA Transmission in mmWave Drone Networks
Nadisanka Rupasinghe, Yavuz Yapici, Ismail Guvenc +2
Physical layer security (PLS) is critically important for emerging wireless communication networks to maintain the confidentiality of the information of legitimate users. In this p…
Adaptive Detection of Structured Signals in Low-Rank Interference
Philip Schniter, Evan Byrne
In this paper, we consider the problem of detecting the presence (or absence) of an unknown but structured signal from the space-time outputs of an array under strong, non-white in…
Comparison of Limited Feedback Schemes for NOMA Transmission in mmWave Drone Networks
Nadisanka Rupasinghe, Yavuz Yapici, Ismail Guvenc +1
Introducing non-orthogonal multiple access (NOMA) transmission to an unmanned aerial vehicle (UAV) based communication network is a promising solution to enhance its spectral effic…
A Graph Theoretic Approach for Training Overhead Reduction in FDD Massive MIMO Systems
Nadisanka Rupasinghe, Yuichi Kakishima, Haralabos Papadopoulos +1
The overheads associated with feedback-based channel acquisition can greatly compromise the achievable rates of FDD based massive MIMO systems. Indeed, downlink (DL) training and u…
