Unmanned aerial vehicle (UAV) communication is anticipated to be widely applied in the
forthcoming fifth-generation wireless networks, due to its many advantages such as low cost …

A coprime array has a larger array aperture as well as increased degrees‐of‐freedom
(DOFs), compared with a uniform linear array with the same number of physical sensors …

This paper presents a multi‐time channel prediction system based on backpropagation (BP)
neural network with multi‐hidden layers, which can predict channel information effectively …

Due to the broadcast nature of wireless radio propagation channels, 5G wireless networks
face serious security threats. Security mechanisms that leverage physical layer …

Wireless physical layer security has attracted great attention in recent years. Although
mobility is an intrinsic property of wireless networks, most of the existing works only consider …

In this paper, we study a secure cooperative transmission system in which a transmitter
(Alice) intends to send a secret message to an authorized receiver (Bob), with the aid of a …

The energy‐constrained devices such as the mobile terminals and nodes of the Internet of
Things make lightweight security schemes an urgent need. The traditional identity …

Land mobile satellite communication and physical layer security are considered as the
promising paradigms in beyond 5G networks. In this paper, we establish the multi-relay …

Due to the spectrum-sharing feature of cognitive radio networks (CRNs) and the
broadcasting nature of wireless channels, providing quality-of-service (QoS) provisioning for …

We study physical layer security in two-cell wireless networks in which a base station (Alice)
intends to send a confidential message to a legitimate user (Bob) with the help of a …
