… improve the secrecy performance of the large-scale networks where no … NOMA networks
can be improved and (2) the asymptotic secrecy outage probability is close to the exact secrecy …

… NOMA enabled wireless networks. As such, we consider a cooperative NOMA network, where
a source uses the NOMA … eavesdropping in this cooperative NOMA network, we propose a …

… the NOMA technique. We analyzed the physical layer security of the network in terms of the
secrecy outage probability (SOP) where the two users have different target secrecy rates. A …

… Therefore, Based on the benefits of both relay networks and NOMA concept, this paper
investigates a new scheme adopting joint NOMA and two-stage relay selection. AF protocol and …

… enhanced performance at NOMA receivers. In this scenario, we use the secrecy probability
to measure the secrecy performance of the system since the perfect secrecy rate is usually …

… been on enhancing the security aspects of the NOMA network … centered on the downlink
NOMA network. We highlight two … selection and adjustment of secrecy performance for each user…

… Apart from enhancing the system performance, NOMA guarantees high fairness
requirements of multiple users through appropriate power allocation scheduling [9, 10]. …

… 2, we plot the illustration of the NOMA network with short-packet communications. In Fig. 2,
multiple users are sorted by their channel gains, ie, |h1|2 >  > |hk|2 >  > |hK|2, where …

… In the NOMA network, the sender transmitted the signals using the random transmit power
to confuse the adversary, which enhanced the covert rate of the NOMA user [12]. Even more …

… secrecy performance are provided. Expressions of the secrecy outage probability (SOP) is
derived for NOMA … ], which can serve as a benchmark of the secrecy performance. While in [8], …
