This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

This article considers an artificial noise (AN)-aided secure MIMO wireless communication
system. To enhance the system security performance, the advanced intelligent reflecting …

In this paper, we investigate methods for reducing the likelihood that a message transmitted
between two multi-antenna nodes is intercepted by an undetected eavesdropper. In …

Secure transmission techniques have been receiving growing attention in recent years, as a
viable, powerful alternative to blocking eavesdrop** attempts in an open wireless …

Consider an MISO channel overheard by multiple eavesdroppers. Our goal is to design an
artificial noise (AN)-aided transmit strategy, such that the achievable secrecy rate is …

Secure communications can be impeded by eavesdroppers in conventional relay systems.
This paper proposes cooperative jamming strategies for two-hop relay networks where the …

This paper studies robust transmission schemes for multiple-input single-output (MISO)
wiretap channels. Both the cases of direct transmission and cooperative jamming with a …

In recent years there has been growing interest in study of multi-antenna transmit designs for
providing secure communication over the physical layer. This paper considers the scenario …

This article provides a comprehensive overview on jamming strategies in the physical layer
for securing wireless communications. As a complement to traditional cryptography-based …

In this paper, we pioneer the study of physical-layer security in heterogeneous networks
(HetNets). We investigate secure communications in a two-tier downlink HetNet, which …
