This paper investigates the physical layer security of a satellite network, whose downlink
spectral resource is shared with a terrestrial cellular network. We propose to employ a multi …

In this letter, we study the secrecy capacity of the classic Wyner's model over the α-μ fading
channels, where α and μ specify the nonlinearity and clustering of fading channels …

This paper investigates the secrecy performance of a two-user downlink non-orthogonal
multiple access systems. Both single-input and single-output and multiple-input and single …

A space and terrestrial integrated network (STIN) converges satellite communication
networks, mobile wireless networking, and the Internet, has greatly extended the scope of …

In this paper, we consider an underlay multiple-input-multiple-output (MIMO) cognitive radio
network (CRN) including a pair of primary nodes, a couple of secondary nodes, and an …

This paper considers a multiple-input-multiple-output (MIMO) cognitive wiretap system over
Nakagami-m channels with generalized selection combining (GSC), where confidential …

To improve national security, government agencies have long been committed to enforcing
powerful surveillance measures on suspicious individuals or communications. In this paper …

This paper considers a secure nonorthogonal multiple access system, where confidential
messages are transmitted from a base station to multiple legitimate destinations and …

The distributed nodes of a Wireless Sensor Network (WSN) cooperate among themselves to
emulate a virtual multi-antenna system to get similar benefits as the conventional MIMO …

This article investigates the physical layer security for a cooperative cognitive radio (CCR)
system with energy-harvesting (EH) technique, which consists of a cognitive source (CS) …
