PAPR Reduction Using Iterative Clipping/Filtering and ADMM Approaches for OFDM-Based Mixed-Numerology Systems
Xiaoran Liu, Xiaoying Zhang, Lei Zhang +4
Mixed-numerology transmission is proposed to support a variety of communication scenarios with diverse requirements. However, as the orthogonal frequency division multiplexing (OFD…
Secure Interference Exploitation Precoding in MISO Wiretap Channel: Destructive Region Redefinition with Efficient Solutions
Ye Fan, Xuewen Liao, Ang Li +1
In this paper, we focus on the physical layer security for a K-user multiple-input-single-output (MISO) wiretap channel in the presence of a malicious eavesdropper, where we propos…
Provisioning Energy-Efficiency and QoS for Multi-Carrier CoMP with Limited Feedback
Mohammad G. Khoshkholgh, Victor C. M. Leung, Kang G. Shin +1
We consider resource allocation (RA) in multi-carrier coordinated multi-point (CoMP) systems with limited feedback, in which a cluster of base stations (BSs), each equipped with mu…
Energy-Efficient Cooperative Caching in UAV Networks
Mohammad G. Khoshkholgh, Victor C. M. Leung
For an unmanned aerial vehicle (UAV) enabled network we investigate the energy-efficiency (EE) of joint caching and cooperative communication (Fog-RAN). Since UAVs are battery- and…
Cross-Layer Scheduling and Beamforming in Smart Grid Powered Small-Cell Networks
Yanjie Dong, Md. Jahangir Hossain, Julian Cheng +1
In the small-cell networks (SCNs) with multiple small-cell base stations (ScBSs), the joint design of beamforming vectors, user scheduling and ScBS sleeping is investigated with th…
Joint Precoding and Power Control in Small-Cell Networks With Proportional-Rate MISO-BC Backhaul
Yanjie Dong, Md. Jahangir Hossain, Julian Cheng +1
In the small-cell networks with multiple-input-single-output broadcasting (MISO-BC) backhauls, the joint dirty-paper coding and power control are investigated for the \mbox{MISO-BC…
Joint Fronthaul Multicast and Cooperative Beamforming for Cache-Enabled Cloud-Based Small Cell Networks: An MDS Codes-Aided Approach
Xiongwei Wu, Qiang Li, Victor C. M. Leung +1
The performance of cloud-based small cell networks (C-SCNs) relies highly on a capacity-limited fronthaul, which degrade quality of service when it is saturated. Coded caching is a…
Cognitive Information Measurements: A New Perspective
Min Chen, Yixue Hao, Hamid Gharavi +1
From a traditional point of view, the value of information does not change during transmission. The Shannon information theory considers information transmission as a statistical p…
Convergence of Edge Computing and Deep Learning: A Comprehensive Survey
Xiaofei Wang, Yiwen Han, Victor C. M. Leung +3
Ubiquitous sensors and smart devices from factories and communities are generating massive amounts of data, and ever-increasing computing power is driving the core of computation a…
Secure Distributed On-Device Learning Networks With Byzantine Adversaries
Yanjie Dong, Julian Cheng, Md. Jahangir Hossain +1
The privacy concern exists when the central server has the copies of datasets. Hence, there is a paradigm shift for the learning networks to change from centralized in-cloud learni…
Joint Long-Term Cache Allocation and Short-Term Content Delivery in Green Cloud Small Cell Networks
Xiongwei Wu, Qiang Li, Xiuhua Li +2
Recent years have witnessed an exponential growth of mobile data traffic, which may lead to a serious traffic burn on the wireless networks and considerable power consumption. Netw…
Enhanced Energy-Efficient Downlink Resource Allocation in Green Non-Orthogonal Multiple Access Systems
Rukhsana Ruby, Shuxin Zhong, Derrick Wing Kwan Ng +2
Despite numerous advantages, non-orthogonal multiple access (NOMA) technique can bring additional interference for the neighboring ultra-dense networks if the power consumption of…
