Physical layer security has drawn significant attention in recent years because of its
advancement in preventing confidential information leakage to eavesdroppers. In this paper …

In this paper, we focus on antieavesdropping design in a multicell multiuser interference
channel coexisting with a multiantenna eavesdropper, in which multiuser interference arises …

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 …

Robust quality-of-service (QoS)-based and secrecy rate-based secure transmission designs
are investigated for a multiple-input single-output system with multiple eavesdroppers and a …

This paper examines linear beamforming methods for secure communications in a multiuser
wiretap channel with a single transmitter, multiple legitimate receivers, and a single …

Millimeter wave (mmWave) communications have been considered as a key technology for
future 5G wireless networks. In order to overcome the severe propagation loss of mmWave …

In this paper, we consider a joint beamforming and jamming design to enhance physical
layer security against potential multiple eavesdroppers in a multiple‐input and single‐output …

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) …

Millimeter wave (mmWave) communications have been considered as a key technology to
enable very high data rate in the fifth-generation applications. Multiple-input-multiple-output …

MU-MIMO beamforming offers great potential for the AP with multiple antennas to serve
multiple receivers concurrently. A key factor to implement the MU-MIMO system is the CSI …
