cooperative relay networks … (NOMA) networks [23], and FD multi-hop wireless networks [24]. …

… NOMA in untrusted relay networks and proposed a novel NOMA-inspired jamming and relaying
… a cooperative DF relay-assisted secure NOMA system, the maximum secure rate for the …

… for all links in the NOMA relaying networks. Without loss of generality, in all simulation
cases, we set that the transmission power of the relay is the same as that of the source station. …
