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 …

We address physical layer security in multiple-input-multiple-output (MISO) communications
in the presence of an unknown passive eavesdropper. Beamforming and artificial noise …

This paper studies different secrecy rate optimization problems for a multiple-input–multiple-
output (MIMO) secrecy channel. In particular, we consider a scenario where a …

Secrecy on the physical layer is a promising technique to simplify the overall cross-layer
secrecy concept. In many recent works on the multiple antenna wiretap channel, perfect …

A Gaussian multiple-input single-output (MISO) wiretap channel model is considered, where
there exists a transmitter equipped with multiple antennas, a legitimate receiver and 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 …

This paper considers a multiple-input multiple-output (MIMO) Gaussian wiretap channel with
a transmitter, a legitimate receiver and an eavesdropper, each equipped with multiple …

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 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 investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …
