A Survey on Non-Orthogonal Multiple Access for 5G Networks: Research Challenges and Future Trends
Zhiguo Ding, Xianfu Lei, George K. Karagiannidis +3
Non-orthogonal multiple access (NOMA) is an essential enabling technology for the fifth generation (5G) wireless networks to meet the heterogeneous demands on low latency, high rel…
Physical Layer Security for Massive MIMO Systems Impaired by Phase Noise
Jun Zhu, Robert Schober, Vijay K. Bhargava
In this paper, we investigate the impact of phase noise on the secrecy performance of downlink massive MIMO systems in the presence of a passive multiple-antenna eavesdropper. Ther…
Analysis and Design of Secure Massive MIMO Systems in the Presence of Hardware Impairments
Jun Zhu, Derrick Wing Kwan Ng, Ning Wang +2
To keep the hardware costs of future communications systems manageable, the use of low-cost hardware components is desirable. This is particularly true for the emerging massive mul…
Per-Antenna Constant Envelope Precoding for Secure Transmission in Large-Scale MISO Systems
Jun Zhu, Ning Wang, Vijay K. Bhargava
Secure transmission in large-scale MISO systems employing artificial noise (AN) is studied under the per-antenna constant envelope (CE) constraint. Achievable secrecy rate of the p…
Linear Precoding of Data and Artificial Noise in Secure Massive MIMO Systems
Jun Zhu, Robert Schober, Vijay K. Bhargava
In this paper, we consider secure downlink transmission in a multi-cell massive multiple-input multiple-output (MIMO) system where the numbers of base station (BS) antennas, mobile…
Secure Transmission in Multi-Cell Massive MIMO Systems
Jun Zhu, Robert Schober, Vijay K. Bhargava
In this paper, we consider physical layer security provisioning in multi-cell massive multiple-input multiple-output (MIMO) systems. Specifically, we consider secure downlink trans…
