Research on Physical Layer Security Strategy in the Scenario of Multiple Eavesdroppers in Cognitive Wireless Networks Based on NOMA

Bio-inspired hybrid lyrebird optimization-based power allocation and relay-selection scheme

“…To demonstrate the efficiency of NOMA system in contrary to the OMA system, resource utilization, error performance, and PA are examined. Furthermore, to improve the application of 5G communications, a number of innovative works have been instigated in the NOMA system [13,14]. In these works, two distinct conditions are considered in the NOMA outage probability analysis.…”
