On Secure NOMA Systems With Transmit Antenna Selection Schemes
Hongjiang Lei,Jianming Zhang,Ki-Hong Park,Peng Xu,Imran Shafique Ansari,Gaofeng Pan,Basel Alomair,Mohamed-Slim Alouini +7 more
TL;DR: This paper investigates the secrecy performance of a two-user downlink non-orthogonal multiple access systems with different transmit antenna selection strategies and finds that the secrecy diversity order for all the TAS schemes with fixed power allocation is zero.
Journal ArticleDOI
Secrecy Capacity Analysis Over $\alpha - \mu $ Fading Channels
TL;DR: The numerical results show that rigorous fading channels are beneficial to the secrecy performance, that is, serious nonlinearity and sparse clustering will lead to the improvement of ASC.
Journal ArticleDOI
Secrecy Outage Performance of Transmit Antenna Selection for MIMO Underlay Cognitive Radio Systems Over Nakagami- $m$ Channels
Hongjiang Lei,Chao Gao,Imran Shafique Ansari,Yongcai Guo,Yulong Zou,Gaofeng Pan,Khalid A. Qaraqe +6 more
TL;DR: This paper investigates the secrecy outage performances of optimal antenna selection and suboptimal antenna selection schemes for MIMO underlay cognitive radio systems over Nakagami- $m$ channels, and compares them with the space-time transmission (STT) scheme.
Journal ArticleDOI
On Secrecy Performance of MISO SWIPT Systems With TAS and Imperfect CSI
TL;DR: The results reveal the impact of the imperfect CSI on the secrecy performance of MISO SWIPT systems in the presence of multiple wiretap channels.
Journal ArticleDOI
Performance Analysis of Physical Layer Security Over Generalized- $K$ Fading Channels Using a Mixture Gamma Distribution
Hongjiang Lei,Huan Zhang,Imran Shafique Ansari,Chao Gao,Yongcai Guo,Gaofeng Pan,Khalid A. Qaraqe +6 more
TL;DR: The closed-form expressions for the average secrecy capacity, secure outage probability, and the probability of strictly positive secrecy capacity are derived and provide a unified form, which can handle several of the well-known composite fading environments as special or limiting cases.
