Statistical Modeling of FSO Fronthaul Channel for Drone-based Networks
Marzieh Najafi, Hedieh Ajam, Vahid Jamali +3
We consider a drone-based communication network, where several drones hover above an area and serve as mobile remote radio heads for a large number of mobile users. We assume that…
NOMA Assisted Wireless Caching: Strategies and Performance Analysis
Zhiguo Ding, Pingzhi Fan, George K. Karagiannidis +2
Conventional wireless caching assumes that content can be pushed to local caching infrastructure during off-peak hours in an error-free manner; however, this assumption is not appl…
A Novel Network NOMA Scheme for Downlink Coordinated Three-Point Systems
Yanshi Sun, Zhiguo Ding, Xuchu Dai +1
In this paper, we propose a network non-orthogonal multiple access (N-NOMA) technique for the downlink coordinated multipoint (CoMP) communication scenario of a cellular network, w…
Enhancing PHY Security of Cooperative Cognitive Radio Multicast Communications
Van-Dinh Nguyen, Trung Q. Duong, Oh-Soon Shin +2
In this paper, we propose a cooperative approach to improve the security of both primary and secondary systems in cognitive radio multicast communications. During their access to t…
Simultaneous Lightwave Information and Power Transfer (SLIPT) for Indoor IoT Applications
Panagiotis D. Diamantoulakis, George K. Karagiannidis
We present the concept of Simultaneous Lightwave Information and Power Transfer (SLIPT) for indoor Internet-of-Things (IoT) applications. Specifically, we propose novel and fundame…
A Survey on Non-Orthogonal Multiple Access for 5G Networks: Research Challenges and Future Trends
Zhiguo Ding, Xianfu Lei, George K. Karagiannidis +3
Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth generation (5G) wireless networks to meet the heterogeneous demands on low latency, high rel…
Millimeter Wave Communications for Future Mobile Networks
Ming Xiao, Shahid Mumtaz, Yongming Huang +8
Millimeter wave (mmWave) communications have recently attracted large research interest, since the huge available bandwidth can potentially lead to rates of multiple Gbps (gigabit…
Beamforming Optimization for Full-Duplex Wireless-powered MIMO Systems
Batu K. Chalise, Himal A. Suraweera, Gan Zheng +1
We propose techniques for optimizing transmit beamforming in a full-duplex multiple-input-multiple-output (MIMO) wireless-powered communication system, which consists of two phases…
Robust Beamforming for Secrecy Rate in Cooperative Cognitive Radio Multicast Communications
Van-Dinh Nguyen, Trung Q. Duong, Oh-Soon Shin +2
In this paper, we propose a cooperative approach to improve the security of both primary and secondary systems in cognitive radio multicast communications. During their access to t…
Physical Layer Security Jamming: Theoretical Limits and Practical Designs in Wireless Networks
Kanapathippillai Cumanan, Hong Xing, Peng Xu +5
Physical layer security has been recently recognized as a promising new design paradigm to provide security in wireless networks. In addition to the existing conventional cryptogra…
Secure communications with cooperative jamming: Optimal power allocation and secrecy outage analysis
Kanapathippillai Cumanan, George C. Alexandropoulos, Zhgiuo Ding +1
This paper studies the secrecy rate maximization problem of a secure wireless communication system, in the presence of multiple eavesdroppers. The security of the communication lin…
