In this paper, we consider a multi-hop decode-and-forward (DF) relaying transmission in
underlay cognitive radio networks. Considering the presence of an eavesdropper that …

In this paper, we introduce transmit antenna selection/maximal-ratio combining (TAS/MRC)
scheme in dual-hop randomize-and-forward (RaF) cognitive multiple-input multiple-output …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …

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 …

This paper studies the physical layer security (PLS) in an underlay cognitive radio (CR)
network. Under an interference constraint set by the primary user, we propose a secure …

To cover remote areas where terrestrial cellular networks may not be available, non-
terrestrial infrastructures such as satellites and unmanned aerial vehicles (UAVs) can be …

In this paper, we investigate the physical-layer security of a secure communication in single-
input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …

Wireless communication systems are vulnerable to eavesdropping attack in which the
attacker overhear the transmitted data in the network. Hence, the physical-layer security is of …

In this paper, we investigate the secrecy performance of dual-hop decode-and-forward
cognitive relay networks taking into account the channel correlation between the main and …

In this paper, we consider a centralized cooperative cognitive radio network (CCRN), where
a primary base station sends a message to a primary user. Meanwhile, a secondary user …
