Cache-Enabled Physical-Layer Security for Video Streaming in Wireless Networks with Limited Backhaul
Lin Xiang, Derrick Wing Kwan Ng, Robert Schober +1
In this paper, we investigate for the first time the benefits of wireless caching for the physical layer security (PLS) of wireless networks. In particular, a caching scheme enabli…
An Overview of Sustainable Green 5G Networks
Qingqing Wu, Geoffrey Ye Li, Wen Chen +2
The stringent requirements of a 1,000 times increase in data traffic and one millisecond round trip latency have made limiting the potentially tremendous ensuing energy consumption…
Multi-Quality Multicast Beamforming based on Scalable Video Coding
Chengjun Guo, Ying Cui, Derrick Wing Kwan Ng +1
In this paper, we consider multi-quality multicast beamforming of a video stream from a multi-antenna base station (BS) to multiple single-antenna users receiving different qualiti…
Capacity of the Two-Hop Relay Channel with Wireless Energy Transfer from Relay to Source and Energy Transmission Cost
Nikola Zlatanov, Derrick Wing Kwan Ng, Robert Schober
In this paper, we investigate a communication system comprised of an energy harvesting (EH) source which harvests radio frequency (RF) energy from an out-of-band full-duplex relay…
Joint Power and Subcarrier Allocation for Multicarrier Full-Duplex Systems
Yan Sun, Derrick Wing Kwan Ng, Robert Schober
In this paper, we investigate resource allocation for multicarrier communication systems employing a full-duplex base station for serving multiple half-duplex downlink and uplink u…
A Survey of Downlink Non-orthogonal Multiple Access for 5G Wireless Communication Networks
Zhiqiang Wei, Jinhong Yuan, Derrick Wing Kwan Ng +2
Non-orthogonal multiple access (NOMA) has been recognized as a promising multiple access technique for the next generation cellular communication networks. In this paper, we first…
