In this paper, we consider a multiple-input-multiple-output (MIMO) system consisting of one
source, one destination, and one eavesdropper, where each node is equipped with an …

In this paper, we propose general-order transmit antenna selection to enhance the secrecy
performance of multiple-input-multiple-output multieavesdropper channels with outdated …

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 …

This paper investigates the secrecy performance of multiple-input multiple-output systems
under generalized α-μ fading conditions. To this end, we focus on two distinct scenarios: 1) …

In this paper, we investigate the secrecy performance for a multiple-input multiple-output
(MIMO) wiretap channel in the presence of a multiantenna eavesdropper. In particular, the …

This paper studies the achievable secrecy performance of multiple-input multiple-output
wiretap channels in the presence of imperfect channel state information (CSI) with practical …

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 …

In this paper, we consider a homogenous multiantenna downlink network, where a passive
eavesdropper intends to intercept the communication between a base station and multiple …

In this paper, we consider secure transmissions in ergodic Rayleigh fast-faded multiple-input
multiple-output multiple-antenna-eavesdropper (MIMOME) wiretap channels with only …

Artificial noise (AN) can be used to confuse eavesdroppers in a physical layer security
system. One of the main issues concerned in AN schemes is how to improve secrecy …
