Joint Pilot Allocation and Robust Transmission Design for Ultra-dense User-centric TDD C-RAN with Imperfect CSI
Cunhua Pan, Hani Mehrpouyan, Yuanwei Liu +2
This paper considers the unavailability of complete channel state information (CSI) in ultra-dense cloud radio access networks (C-RANs). The user-centric cluster is adopted to redu…
Physical Layer Security in Uplink NOMA Multi-Antenna Systems with Randomly Distributed Eavesdroppers
Gerardo Gomez, Francisco J. Martin-Vega, F. Javier Lopez-Martinez +2
The physical layer security of uplink non-orthogonal multiple access (NOMA) is analyzed. A stochastic geometry approach is applied to analyze the coverage probability and the effec…
Non-orthogonal Multiple Access in Large-Scale Heterogeneous Networks
Yuanwei Liu, Zhijin Qin, Maged Elkashlan +2
In this paper, the potential benefits of applying non-orthogonal multiple access (NOMA) technique in -tier hybrid heterogeneous networks (HetNets) is explored. A promising new t…
Optimal User Scheduling and Power Allocation for Millimeter Wave NOMA Systems
Jingjing Cui, Yuanwei Liu, Zhiguo Ding +2
This paper investigates the application of non-orthogonal multiple access (NOMA) in millimeter wave (mmWave) communications by exploiting beamforming, user scheduling and power all…
Enhancing the Physical Layer Security of Non-orthogonal Multiple Access in Large-Scale Networks
Yuanwei Liu, Zhijin Qin, Maged Elkashlan +2
This paper investigates the physical layer security of non-orthogonal multiple access (NOMA) in large-scale networks with invoking stochastic geometry. Both single-antenna and mult…
