Cognitive radio network is an emerging solution to deal with spectrum scarcity and to utilize
the radio spectrum in opportunistic and efficient manner. Secure data transmission is one of …

This study investigates the secrecy outage performance of a single‐input multiple‐output
underlay cognitive radio network (CRN) with outdated channel state information (CSI). The …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

This paper investigates the secrecy outage performance of Multiple Input Multiple Output
(MIMO) secondary nodes for underlay Cognitive Radio Network (CRN) over α–μ fading …

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 …

This paper investigates the secrecy outage performance of transmit antenna selection
(TAS)/maximal ratio combining (MRC) in multiple-input-multiple-output (MIMO) cognitive …

We investigate the secrecy outage performance of maximal ratio combining (MRC) in
cognitive radio networks over Rayleigh fading channels. In a single-input multiple-output …

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 …

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