Relay-Selection Improves the Security-Reliability Trade-off in Cognitive Radio Systems
Yulong Zou, Benoit Champagne, Wei-Ping Zhu +1
We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a secondary destination (SD) and multiple secondary relays (SRs) in the presence of an eavesd…
Outage Analysis of Multi-Relay Selection for Cognitive Radio with Imperfect Spectrum Sensing
Yulong Zou, Jia Zhu, Baoyu Zheng
In this paper, we examine the outage performance of a cognitive relay network, which is comprised of a secondary transmitter (ST), multiple decode-and-forward (DF) relays and a sec…
Secrecy Outage Probability Analysis of Multi-User Multi-Eavesdropper Wireless Systems
Yulong Zou, Jia Zhu, Gongpu Wang +1
In this paper, we explore the physical-layer security of a multi-user wireless system that consists of multiple users intending to transmit to a base station (BS), while multiple e…
Secrecy Outage and Diversity Analysis of Cognitive Radio Systems
Yulong Zou, Xuelong Li, Ying-Chang Liang
In this paper, we investigate the physical-layer security of a multi-user multi-eavesdropper cognitive radio system, which is composed of multiple cognitive users (CUs) transmittin…
Improving Physical-Layer Security in Wireless Communications Using Diversity Techniques
Yulong Zou, Jia Zhu, Xianbin Wang +1
Due to the broadcast nature of radio propagation, the wireless transmission can be readily overheard by unauthorized users for interception purposes and is thus highly vulnerable t…
