The fifth generation (5G) wireless systems are expected to meet an continuously increasing
demand for wireless applications such as wide radio coverage and high data rate [1]. Due to …

This paper considers an artificial noise (AN)-aided transmit design for multi-user MIMO
systems with integrated services. Specifically, two sorts of service messages are combined …

This paper extends our previous work on multiple‐input–multiple‐output multiantenna
eavesdropper–based wiretap channels aimed at fundamentally proposing optimally secure …

5G is expected to serve completely heterogeneous scenarios where devices with low or
high software and hardware complexity will coexist. This entails a security challenge …

In this paper, we consider a MIMO wiretap system in wireless sensor networks (WSNs),
where the confidential signal sent to the legitimate receive (Bob) may be eavesdropped by …

Information security is one of the most critical issues in wireless networks as the signals
transmitted through wireless medium are more vulnerable for interception. Although the …

In this article, we first investigate secure communications for a two-hop interference channel
relay system with imperfect channel estimation in the wireless Internet of Things (IoT), where …

In this paper, we study robust resource allocation for the multi-user full-duplex (FD) multiple-
input multiple-output (MIMO) communication systems. Particularly, we aim at minimizing …

In this paper, we study channel-aware (CA) randomization for secure transmissions in a
multicarrier system based on partial channel state information (CSI). In order to see the …

This paper investigates a secure wireless-powered multiantenna multicasting system, where
multiple power beacons (PBs) supply power to a transmitter in order to establish a reliable …
