In wireless communication, the transmitter (Alice) can send artificial noise (AN) to interfere
with the eavesdropper (Eve). This letter considers the AN MIMO scenario, ie, both Alice and …

In this paper, we consider max-min fairness for a downlink two-user multi-input single-output
(MISO) system with imperfect channel state information available at transmitter (CSIT) taking …

This paper considers a unicast multiuser multiple-input single-output (MISO) downlink
system overheard by multiple single-antenna eavesdroppers. The objective is to jointly …

Optimal signaling for secrecy rate maximization in Gaussian MIMO wiretap channels is
considered. While this channel has attracted a significant attention recently and a number of …

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

Recently, there has been growing interest in secure communication via multi-antenna
physical-layer designs. In this paper, we consider a transmit covariance design for a secrecy …

The problem of optimal power allocation between the information-bearing signal and the
artificial noise (AN) signal is addressed in this letter to enhance the physical layer security of …

In this paper, we consider the robust secure beamformer design for multiple-input-single-
output wiretap channels. Assuming that the eavesdroppers' channels are only partially …

The secrecy rate maximization with the artificial noise (AN) aided beamforming for the
multipel-input-single-output (MISO) wiretap channel is addressed in this paper under the …

In this paper, we consider a single-cell downlink multi-user multi-input multi-output (MU-
MIMO) system in which multiple eavesdroppers coexist. The eavesdroppers overhear …
