As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

In this article, we study a robust beamforming design for multiuser multiple-input–multiple-
output secrecy networks with simultaneous wireless information and power transfer (SWIPT) …

In this paper, we investigate simultaneous wireless information and power transfer systems
for multiuser multiple-input single-output secure broadcasting channels. Considering …

In this paper, an energy harvesting scheme for a multi-user multiple-input-multiple-output
secrecy channel with artificial noise (AN) transmission is investigated. Joint optimization of …

This paper investigates secrecy rate optimization problems for a multiple-input-single-output
(MISO) secrecy channel in the presence of multiple multiantenna eavesdroppers …

This paper studies the secrecy rate maximization problem of a secure wireless
communication system in the presence of multiple eavesdroppers. The security of the …

In future practical deployments of massive multi-input multi-output (MIMO) systems, the
number of radio-frequency (RF) chains at the base stations (BSs) may be much smaller than …

This paper studies the use of multi-antenna harvest-and-jam (HJ) helpers in a multi-antenna
amplify-and-forward (AF) relay wiretap channel assuming that the direct link between the …

We propose a robust beamforming design for non-orthogonal multiple access-based
multiple-input single-output downlink systems. In particular, the robust power minimization …

This letter generalizes the precoding-aided spatial modulation (PSM) to a multiuser (MU)
downlink scenario. With precoding vectors elaborately designed, a proposed MU-PSM …
