Secrecy Outage Performance Analysis for Cooperative NOMA Over Nakagami- $m$ Channel

IEEE Access, 2019
In this paper, we investigate the secrecy outage performance of a typical cooperative downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel, in which the base station transmits a superimposed signal to two users via a relay.
