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…
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…
On the Secrecy Outage Capacity of Physical Layer Security in Large-Scale MIMO Relaying Systems with Imperfect CSI
Xiaoming Chen, Lei Lei, Huazi Zhang +1
In this paper, we study the problem of physical layer security in a large-scale multiple-input multiple-output (LS-MIMO) relaying system. The advantage of LS-MIMO relaying systems…
Energy-Efficient Optimization for Physical Layer Security in Multi-Antenna Downlink Networks with QoS Guarantee
Xiaoming Chen, Lei Lei
In this letter, we consider a multi-antenna downlink network where a secure user (SU) coexists with a passive eavesdropper. There are two design requirements for such a network. Fi…
