In this paper, we consider the problem of full-duplex covert millimeter wave (mmWave)
communications, where a mmWave transmitter (Alice) sends information signals to its …

In this work, we consider a secure precoding optimization problem for the artificial noise
(AN) scheme in multiple-input single-output (MISO) wiretap channels. In previous …

In this paper, we focus on antieavesdropping design in a multicell multiuser interference
channel coexisting with a multiantenna eavesdropper, in which multiuser interference arises …

Artificial noise (AN), aiming to disturb the eavesdropper while avoiding the influence on the
legitimate receiver, has arisen as an excellent technology for improving the physical-layer …

This paper considers a multiple-input-multiple-output (MIMO) energy-harvesting (EH)
system, which is made up of a source (S) and a destination (D) as well as an eavesdropper …

The security of information over wireless channels has always been an important aspect of
wireless communication research. In this paper, the secrecy performance of a spatial …

In this article, we focus on the joint design of channel training and data transmission for
secure ultrareliable and low-latency communications (URLLCs) in mission-critical Internet of …

The studies on the conventional transmit antenna selection (TAS) in multiple-input, multiple-
output, multiple-antenna eavesdropper (MIMOME) channel have been focused on …

The existing investigations on artificial noise (AN) security systems assumed that only null
spaces are used to send AN signals, and all eigen-subchannels should be used to transmit …

To protect military broadcasting against both hostile interference and eavesdropping, an
artificial noise (AN) sheltered frequency hopping (FH) broadcasting (ANS-FHB) architecture …
