Cache-Enabled Physical Layer Security for Video Streaming in Backhaul-Limited Cellular Networks
Lin Xiang, Derrick Wing Kwan Ng, Robert Schober +1
In this paper, we propose a novel wireless caching scheme to enhance the physical layer security of video streaming in cellular networks with limited backhaul capacity. By proactiv…
On the Capacity of SWIPT Systems with a Nonlinear Energy Harvesting Circuit
Rania Morsi, Vahid Jamali, Derrick Wing Kwan Ng +1
In this paper, we study information-theoretic limits for simultaneous wireless information and power transfer (SWIPT) systems employing a practical nonlinear radio frequency (RF) e…
Robust and Secure Resource Allocation for Full-Duplex MISO Multicarrier NOMA Systems
Yan Sun, Derrick Wing Kwan Ng, Jun Zhu +1
In this paper, we study the resource allocation algorithm design for multiple-input single-output (MISO) multicarrier non-orthogonal multiple access (MC-NOMA) systems, in which a f…
Power-Efficient and Secure WPCNs with Hardware Impairments and Non-Linear EH Circuit
Elena Boshkovska, Derrick Wing Kwan Ng, Linglong Dai +1
In this paper, we design a robust resource allocation algorithm for a wireless-powered communication network (WPCN) taking into account residual hardware impairments (HWIs) at the…
Resource Allocation for MC-NOMA Systems with Cognitive Relaying
Yan Sun, Derrick Wing Kwan Ng, Robert Schober
In this paper, we investigate the resource allocation algorithm design for cooperative cognitive relaying multicarrier non-orthogonal multiple access (MC-NOMA) systems. In particul…
Secure Video Streaming in Heterogeneous Small Cell Networks with Untrusted Cache Helpers
Lin Xiang, Derrick Wing Kwan Ng, Robert Schober +1
This paper studies secure video streaming in cache-enabled small cell networks, where some of the cache-enabled small cell base stations (BSs) helping in video delivery are untrust…
