Secrecy Outage Probability Analysis for Downlink NOMA with Imperfect SIC at Untrusted Users [PDF]

, 2023
Non-orthogonal multiple access (NOMA) has come to the fore as a spectrally efficient technique for fifth-generation networks and beyond. At the same time, NOMA faces severe security issues in the presence of untrusted users due to successive interference
