In this paper, we investigate the artificial noise-aided jamming design for a transmitter
equipped with large antenna array in Rician fading channels. We figure out that when the …

The general Gaussian multiple-access wiretap channel (GGMAC-WT) and the Gaussian two-
way wiretap channel (GTW-WT) are considered. In the GGMAC-WT, multiple users …

We study, in this paper, the secrecy performance of a multi-user (MU) multiple-input single-
output visible light communication broadcast channel with confidential messages. The …

In this paper, we examine the secrecy performance of two-way relaying between a large-
scale multiple antenna base station (BS) and a single antenna mobile user (MU) in the …

We consider precoder and artificial noise (AN) design for multi-antenna wiretap channels
under the finite-alphabet input assumption. We assume that the transmitter has access to the …

We consider the problem of secure communication in wireless fading channels in the
presence of non-colluding passive eavesdroppers. The transmitter has multiple antennas …

This paper is concerned with an optimization problem in a two-hop relay wiretap channel,
wherein multiple multi-antenna relays collaboratively amplify and forward (AF) information …

Physical (PHY) layer security approaches for wireless communications can prevent
eavesdropping without upper layer data encryption. However, they are hampered by …

We consider the problem of secure communication with multiantenna transmission in fading
channels. The transmitter simultaneously transmits an information-bearing signal to the …

Wyner's wiretap channel is generalized to the case when the sender, the receiver and the
eavesdropper have multiple antennas. We consider two cases: the deterministic case and …
