Performance of Full-Duplex AF Relaying in the Presence of Residual Self-Interference
TL;DR: This paper shows that FD linear relaying systems with a suitable precoder can attain the same diversity function as their half-duplex (HD) counterparts, and shows that HD orthogonal AF using a superposition constellation is asymptotically optimal in terms of maximum coding gain.
Journal ArticleDOI
Physical layer security in wireless cooperative relay networks: state of the art and beyond
Leonardo Jimenez Rodriguez,Nghi H. Tran,Trung Q. Duong,Tho Le-Ngoc,Maged Elkashlan,Sachin Shetty +5 more
TL;DR: This article presents a comprehensive summary of current state-of-theart PHY security concepts in wireless relay networks, and outlines important future research directions in relaying topologies, full-duplex relaying, and cross-layer design that can ignite new interests and ideas on the topic.
Journal ArticleDOI
Secure Transmission with Optimal Power Allocation in Untrusted Relay Networks
TL;DR: The problem of secure transmission in two-hop amplify-and-forward untrusted relay networks and the ergodic secrecy capacity (ESC) is considered and compact expressions for the ESC in the high signal-to-noise ratio regime are presented.
Journal ArticleDOI
Optimal Power Allocation and Capacity of Full-Duplex AF Relaying under Residual Self-Interference
TL;DR: Comparisons between the half-duplex and FD systems are carried out, where analytical and simulation results reveal that the FD system is superior in high source power regions with either fixed or large power constraints at the relay.
Journal ArticleDOI
Space Modulation With CSI: Constellation Design and Performance Evaluation
TL;DR: Two novel methods to design the transmit vectors using CSIT such that the distance between each pair of constellation vectors at the receiver becomes larger, which, in turn, reduces the symbol error rate (SER) of the system.
