Physical Layer Security for Keyhole-based NOMA Downlink Systems with a Multi-antenna Eavesdropper

Journal of Telecommunications and Information Technology
This paper investigates the physical layer security of downlink nonorthogonal multiple access (NOMA) systems operating over a degenerate keyhole channel in the presence of a multi-antenna eavesdropper. We propose a joint antenna selection framework with
