Optimal Power Allocation for A Massive MIMO Relay Aided Secure Communication
Jian Chen, Xiaoming Chen, Wolfgang Gerstacker
In this paper, we address the problem of optimal power allocation at the relay in two-hop secure communications under practical conditions. To guarantee secure communication during…
Large-Scale MIMO Relaying Techniques for Physical Layer Security: AF or DF?
Xiaoming Chen, Lei Lei, Huazi Zhang +1
In this paper, we consider a large scale multiple input multiple output (LS-MIMO) relaying system, where an information source sends the message to its intended destination aided b…
Multi-Antenna Relay Aided Wireless Physical Layer Security
Xiaoming Chen, Caijun Zhong, Chau Yuen +1
With growing popularity of mobile Internet, providing secure wireless services has become a critical issue. Physical layer security (PHY-security) has been recognized as an effecti…
On Interference Alignment with Imperfect CSI: Characterizations of Outage Probability, Ergodic Rate and SER
Xiaoming Chen, Chau Yuen
In this paper, we give a unified performance analysis of interference alignment (IA) over MIMO interference channels. Rather than the asymptotic characterization, i.e. degree of fr…
Optimal Power Allocation for Secure Communications in Large-Scale MIMO Relaying Systems
Jian Chen, Xiaoming Chen, Xiumin Wang +1
In this paper, we address the problem of optimal power allocation at the relay in two-hop secure communications. In order to solve the challenging issue of short-distance intercept…
Energy-Efficient Power Allocation for Secure Communications in Large-Scale MIMO Relaying Systems
Jian Chen, Xiaoming Chen, Tao Liu +1
In this paper, we address the problem of energy-efficient power allocation for secure communications in an amplify-and-forward (AF) large-scale multiple-input multiple-output (LS-M…
