In this article, we investigate the performance of a piece-wise linear model of energy
harvesting-based multiuser overlay spectrum sharing system. Herein, an energy …

We integrate a wireless powered communication network with a cooperative cognitive radio
network, where multiple secondary users (SUs) powered wirelessly by a hybrid access point …

In this paper, we study the reliability-security tradeoff for a secondary network in an
underday cognitive radio (CR) environment. In the proposed protocol, a secondary …

In this paper, we investigate the performance of a non-linear energy harvesting based
overlay spectrum sharing system. Herein, an energy-constrained secondary node acts as a …

In this paper, we propose an energy harvesting-based overlay hybrid satellite-terrestrial
spectrum sharing system which exploits both direct and relay links from a primary satellite …

In this paper, we study physical-layer security (PLS) issue in underlay cognitive radio (UCR)
networks in presence of multiple primary users (PUs). In particular, we propose three relay …

In this paper, we evaluate performances of various transmit antenna selection (TAS)
protocols in underlay cognitive radio network under impact of hardware impairments. In …

In this paper, a cognitive hybrid satellite-terrestrial relay network with power splitting-based
energy harvesting (EH) has been proposed. Herein, a primary satellite source coexists with …

Tôi cũng xin chân thành cảm ơn quý thầy cô thuộc Phòng Đào tạo và Khoa học Công nghệ.
Đặc biệt, tôi xin cảm ơn cô Nguyễn Thị Phương Thảo đã hết lòng hỗ trợ cho khóa học của …

In this paper, we study physical-layer security issue of secondary networks in cognitive radio
(CR). In the considered system model, a secondary source communicates with a secondary …
