… For an untrusted cooperative network, the relay which is generally implemented …
untrusted nodes is becoming an increasing concern in 5G candidate applications, eg, uplink/downlink …

… outage probability of the transmitter-relay cooperation under unreliable backhauls and the
eavesdropping collaboration with MRC across K eavesdroppers and over two time slots is …

… relaying with an untrusted relay is as follows: In the first phase, the source transmits secret
information and the destination sends an AN signal to the relay. … consider a downlink scenario …

… to the case where the relay is an untrusted node, and cooperative jamming technique is …
We consider a down-link NOMA cooperative communication system, in which a source node …

… In our cooperative CR NOMA system, ST acts as an untrusted relay and hence, the
instantaneous secrecy capacity C s can be expressed as(14) C S = 1 2 log 2 ( 1 + γ PD ) - 1 2 log 2 ( …
