Secure Energy Efficiency Optimization for MISO Cognitive Radio Network with Energy Harvesting
Miao Zhang, Kanapathippillai Cumanan, Alister Burr
This paper investigates a secure energy efficiency (SEE) optimization problem in a multiple-input single-output (MISO) underlay cognitive radio (CR) network. In particular, a multi…
Limited Feedback Scheme for Device to Device Communications in 5G Cellular Networks with Reliability and Cellular Secrecy Outage Constraints
Faezeh Alavi, Nader Mokari, Mohammad R. Javan +1
In this paper, we propose a device to device (D2D) communication scenario underlaying a cellular network where both D2D and cellular users (CUs) are discrete power-rate systems wit…
Robust Beamforming Techniques for Non-Orthogonal Multiple Access Systems with Bounded Channel Uncertainties
Faezeh Alavi, Kanapathippillai Cumanan, Zhiguo Ding +1
In this letter, we propose a robust beamforming design for non-orthogonal multiple access (NOMA) based multiple-input single-output (MISO) downlink systems. In particular, the robu…
Optimal Power Allocation Scheme for Non-Orthogonal Multiple Access with -Fairness
Peng Xu, Kanapathippillai Cumanan
This paper investigates the optimal power allocation scheme for sum throughput maximization of non-orthogonal multiple access (NOMA) system with -fairness. In contrast to the ex…
Robust Geometry-Based User Scheduling for Large MIMO Systems Under Realistic Channel Conditions
Manijeh Bashar, Alister G. Burr, Dick Maryopi +2
The problem of user scheduling with reduced overhead of channel estimation in the uplink of Massive multiple-input multiple-output (MIMO) systems has been considered. A geometry-ba…
Physical Layer Security Jamming: Theoretical Limits and Practical Designs in Wireless Networks
Kanapathippillai Cumanan, Hong Xing, Peng Xu +5
Physical layer security has been recently recognized as a promising new design paradigm to provide security in wireless networks. In addition to the existing conventional cryptogra…
Secure communications with cooperative jamming: Optimal power allocation and secrecy outage analysis
Kanapathippillai Cumanan, George C. Alexandropoulos, Zhgiuo Ding +1
This paper studies the secrecy rate maximization problem of a secure wireless communication system, in the presence of multiple eavesdroppers. The security of the communication lin…
