Secure D2D underlaying cellular communication based on artificial noise assisted
Tongxin xuebao, 2015 A secure communication scheme based on artificial noise assisted from base station(BS)was proposed to improve the system secrecy rate of the D2D underlaying cellular.Firstly,the system secrecy rate was modeled.Then the BS with multi-antennas added ...

On multiuser secrecy rate in flat fading channel
MILCOM 2009 - 2009 IEEE Military Communications Conference, 2009 We consider a physical layer security based on the wiretap channel for wireless communication systems in which there are one transmitter and multiple receivers/users who report their channel state information (CSI) to the transmitter. This scenario is practically useful since it models the forward link of cellular systems where the systems can take ...

The Gaussian Multiple Access Wire-Tap Channel with Collective Secrecy Constraints
, 2006 We consider the Gaussian Multiple Access Wire-Tap Channel (GMAC-WT). In this scenario, multiple users communicate with an intended receiver in the presence of an intelligent and informed wire-tapper who receives a degraded version of the signal at the ...

Secure Communication in Millimeter Wave Relaying Networks
IEEE Access, 2019 The use of relay can expand the coverage of millimeter-wave (mmWave) signals, whereas it may increase the risk of information leakage due to the additional link from source to relay.
