Mitigating Pilot Contamination Through Location-Aware Pilot Assignment in Massive MIMO Networks
Noman Akbar, Shihao Yan, Nan Yang +1
We propose a novel location-aware pilot assignment scheme to mitigate pilot contamination in massive multiple-input multiple-output (MIMO) networks, where the channels are subjecte…
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…
Low Complexity Power Allocation Schemes in Regenerative Multi-user Relay Networks
Arvind Chakrapani, Robert Malaney, Jinhong Yuan
In relay assisted wireless communications, the multi-source, single relay and single destination system (an -1-1 system) is of growing importance, due to the increased demand fo…
Secure Communication in Uplink Transmissions: User Selection and Multiuser Secrecy Gain
Hao Deng, Hui-Ming Wang, Jinhong Yuan +2
In this paper, we investigate secure communications in uplink transmissions, where there are a base station (BS) with M receive antennas, K mobile users each with a single antenna,…
Power-Efficient Resource Allocation for MC-NOMA with Statistical Channel State Information
Zhiqiang Wei, Derrick Wing Kwan Ng, Jinhong Yuan
In this paper, we study the power-efficient resource allocation for multicarrier non-orthogonal multiple access (MC-NOMA) systems. The resource allocation algorithm design is formu…
Artificial-Noise Aided Secure Transmission in Large Scale Spectrum Sharing Networks
Yansha Deng, Lifeng Wang, Syed Ali Raza Zaidi +2
We investigate beamforming and artificial noise generation at the secondary transmitters to establish secure transmission in large scale spectrum sharing networks,where multiple no…
Non-orthogonal Multiple Access in Large-Scale Underlay Cognitive Radio Networks
Yuanwei Liu, Zhiguo Ding, Maged Elkashlan +1
In this paper, non-orthogonal multiple access (NOMA) is applied to large-scale underlay cognitive radio (CR) networks with randomly deployed users. In order to characterize the per…
Physical Layer Security in Heterogeneous Cellular Networks
Hui-Ming Wang, Tong-Xing Zheng, Jinhong Yuan +2
The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G cellular networks. This paper comprehensively studies physical layer security in a multi-ti…
