Secrecy rate with friendly full-duplex relay

2015 IEEE Wireless Communications and Networking Conference (WCNC), 2015
This paper considers the use of a friendly full-duplex (FD) relay to increase the secrecy rate over a fading channel between the legitimate source and destination in the presence of a naive or informed eavesdropper. Naive eavesdropper can only decode the received signals either from the source or from the relay, while informed eavesdropper can overhear

Secrecy Rate Maximization with Artificial Noise for Pinching-Antenna Systems

IEEE International Symposium on Personal, Indoor and Mobile Radio Communications
Security is emerging as a critical performance metric for next-generation wireless networks, but conventional multiple-input-multiple-output (MIMO) systems often suffer from severe path loss and are vulnerable to nearby eavesdroppers due to their fixed ...
