In this paper, we investigate the precoding scheme for multiple-input multiple-output multiple
antennas eavesdropper (MIMOME) channels under the constraint of finite-alphabet inputs to …

This paper proposes a framework for the artificial noise assisted secure transmission in
multiple-input, multiple-output, multiple antenna eavesdropper (MIMOME) wiretap channels …

In this paper, we investigate transmit beamforming schemes based on artificial interference
for physical layer security in a multi-antenna wiretap channel. We consider the case where …

In this letter, we investigate the physical-layer security of an active reconfigurable intelligent
surface (ARIS)-assisted uplink single-input multi-output non-orthogonal multiple access …

We propose and analyze transmit antenna selection (TAS) to enhance physical layer
security in a wiretap channel with NA antennas at the transmitter, NB antennas at 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 …

In this paper, we investigate the problem of jointly designing optimum linear precoder and
decoder with secrecy constraints, where two legitimate parties communicate in the presence …

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 …

In this work, a Gaussian two-user MIMO interference channel is considered in the presence
of an external eavesdropper whose channel is completely unknown to the legitimate …

In this paper, considering both the antenna correlation and the channel correlation between
the legitimate receiver and the eavesdropper, we comprehensively investigate the secrecy …
