Secure transfer of wireless information is becoming a critical issue in multi-user interference
networks. In this paper, we consider secure transmission from a source (Alice) to a legitimate …

The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-
output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel …

This paper considers secure transmission design for multiple-input-single-output multiple
multi-antenna eavesdroppers networks with finite alphabet inputs. To improve the …

This paper studies robust transmission schemes for multiple-input single-output (MISO)
wiretap channels. Both the cases of direct transmission and cooperative jamming with a …

This paper investigates the impact of realistic propagation conditions on the achievable
secrecy performance of multiple-input multiple-output systems in the presence of an …

In this letter, we aim to achieve secure communication for a multiple-input single-output
(MISO) wiretap channel in the presence of multiple non-colluding eavesdroppers. It is …

We consider a multi-link interference network that is tapped by an external eavesdropper. To
conceal information from the eavesdropper, legitimate links are equipped with transmitter …

In this paper, we investigate methods for reducing the likelihood that a message transmitted
between two multi-antenna nodes is intercepted by an undetected eavesdropper. In …

An intelligent reflecting surface (IRS) is proposed to enhance the physical layer security in
the Rician fading channel wherein the angular direction of the eavesdropper (ED) is aligned …

In this paper, we investigate a multiuser MIMO downlink with imperfect channel state
information (CSI) from the physical-layer security provision. In a classical transmitter (Alice) …
