We investigate the optimal physical-layer secure transmission with artificial noise in the
wiretap channel with N antennas at the transmitter, a single antenna at the receiver, and M …

We analyze and optimize the secrecy performance of artificial noise (AN) in multi-input
single-output wiretap channels with multiple antennas at the transmitter and a single …

We examine the secrecy performance of three artificial-noise-aided secure transmission
schemes, namely, the partially adaptive, fully adaptive, and ON-OFF schemes. To this end …

For physical layer security with multiple antennas over wireless channels, we consider an
artificial noise-aided secure beamforming system. A transmitter can send the confidential …

This paper studies the artificial noise (AN) aided beamforming design in the multiple-input,
single-output, and multiple-eavesdropper wiretap channel from the perspective of secrecy …

We consider transmission of confidential data over multiple-input single-output multiple-
eavesdropper (MISOME) Rayleigh-fading wiretap channels. The transmitter has access to …

We design a novel artificial-noise-aided secure ON-OFF transmission scheme in a wiretap
channel. We consider a practical scenario, where the multi-antenna transmitter only obtains …

The artificial noise (AN) scheme is an efficient strategy for enhancing the secrecy rate of a
multiple-input-single-output channel in the presence of a passive eavesdropper, whose …

In this paper, we study the secure multi-antenna transmission with artificial noise (AN) under
slow fading channels coexisting with randomly located eavesdroppers. We provide a …

In this letter, we consider physical layer security in multiple-input single-output (MISO) fading
wiretap channels, where the transmitter utilizes a jamming-aided precoding transmission …
