This paper studies the secure multiple-antenna transmission in slow fading channels for the
cognitive radio network, where a multiple-input, single-output, multieavesdropper (MISOME) …

This paper investigates the secrecy performance of a single-input multiple-output (SIMO)
based underlay cognitive radio networks. In particular, a single-antenna secondary …

In this letter, we consider a single-input multiple-output cognitive wiretap system over
generalized-K channels, where the eavesdropper overhears the transmission from the …

The authors study the secure transmission design in random cognitive radio networks where
the primary users, the secondary users and the eavesdroppers are randomly distributed …

In this paper, we consider multiple-input single-output multi-eavesdropper cognitive radio
networks (MISOME-CRNs), where a secondary user (SU) aims to transmit confidential …

In this paper, we investigate the secrecy performance of a multiantenna cognitive wiretap
network, where the secondary transmitter (Alice) communicates with the secondary receiver …

Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage
multitier hierarchical networks. Securing data transmission in these networks is of the utmost …

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 …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

In this paper, we address the physical-layer security issue of a secondary user (SU) in a
spectrum-sharing cognitive radio network (CRN) from an information-theoretic perspective …
