Physical-Layer Security for Untrusted UAV-Assisted Full-Duplex Wireless Networks
Theshani Nuradha, Kasun T. Hemachandra, Tharaka Samarasinghe +1
The paper considers physical layer security (PLS) of an untrusted unmanned aerial vehicle (UAV) network, where a multitude of UAVs communicate in full-duplex (FD) mode. A source-ba…
Resource Allocation in Dynamic DF Relay for SWIPT Network with Circuit Power Consumption
Bhathiya Pilanawithana, Saman Atapattu, Jamie Evans
This paper considers simultaneous wireless information and power transfer (SWIPT) over a dual-hop dynamic decode-and-forward (DF) relay network with the power-splitting (PS) energy…
Channel Estimation for Ambient Backscatter Communication Systems with Massive-Antenna Reader
Wenjing Zhao, Gongpu Wang, Saman Atapattu +2
Ambient backscatter, an emerging green communication technology, has aroused great interest from both academia and industry. One open problem for ambient backscatter communication…
Location-Based Optimum Relay Selection in Random Spatial Networks
Saman Atapattu, Hazer Inaltekin, Jamie Evans
This paper investigates the location-based relay selection problem, where the source node chooses its relay from a set of spatially deployed decode-and-forward relays. The advantag…
Eigenvalue Based Detection of a Signal in Colored Noise: Finite and Asymptotic Analyses
Lahiru D. Chamain, Prathapasinghe Dharmawansa, Saman Atapattu +1
Signal detection in colored noise with an unknown covariance matrix has a myriad of applications in diverse scientific/engineering fields. The test statistic is the largest general…
Opportunistic Wireless Energy Transfer in Point-to-Point Links
Amanthi Thudugalage, Saman Atapattu, Jamie Evans
In this paper we consider wireless energy transfer for a point-to-point link. The energy transmitter sees a finite number of independent channel realizations, and, armed with (caus…
Average Transmission Success Probability Bound for SWIPT Relay Networks
Bhathiya Pilanawithana, Saman Atapattu, Jamie Evans
Wireless energy transferring technology offers a constant and instantaneous power for low-power applications such as Internet of Things (IoT) to become an affordable reality. This…
Detection of a Signal in Colored Noise: A Random Matrix Theory Based Analysis
Lahiru D. Chamain, Prathapasinghe Dharmawansa, Saman Atapattu +1
This paper investigates the classical statistical signal processing problem of detecting a signal in the presence of colored noise with an unknown covariance matrix. In particular,…
