ZF-SIC Based Individual Secrecy in SIMO Multiple Access Wiretap Channel
IEEE Access, 2017 In this paper, a decoding method of joint zero-forcing and successive interference cancellation (ZF-SIC) is put forward to assist the study of the individual secrecy in the quasi-static Rayleigh fading single-input multiple-output multiple access wiretap

Secrecy Rate Maximizing Beamforming Schemes for the DF Relay Wiretap Channels
IEEE Access, 2018 We consider beamforming schemes for the multi-antenna decode-and-forward (DF) relays that maximize the secrecy rate (SR) in the relay wiretap channel. Both full-duplex (FD) and half-duplex (HD) relays are considered, where the FD relay fights the loop ...
