Spectrum sharing and successive interference cancellation (SIC) techniques used in power-
domain non-orthogonal multiple access (NOMA) systems impose secrecy challenges …

In this paper, we propose a novel beamforming design to enhance physical layer security of
a non-orthogonal multiple access (NOMA) system with the aid of artificial noise (AN). The …

In this paper, we analyze the secrecy and throughput of multiple-input single-output (MISO)
energy harvesting (EH) Internet of Things (IoT) systems, in which a multi-antenna base …

This article studies the reliable and secure communications for a wireless-powered non-
