Decoding-Order-Aware Secrecy Rate Maximization in IRS-Assisted Untrusted NOMA Under Imperfect SIC
This work investigates an IRS-assisted downlink NOMA system with untrusted users under imperfect SIC, where internal eavesdropping-users intercepting each other's messages-poses distinct security challenges absent in conventional external-eavesdropper models. A key contribution is the systematic analysis of all possibl...
