Secure User Pairing and Power Allocation for Downlink Non-Orthogonal Multiple Access against External Eavesdropping

We propose a secure user pairing (UP) and power allocation (PA) strategy for a downlink Non-Orthogonal Multiple Access (NOMA) system when there exists an external eavesdropper. The secure transmission of data through the downlink is constructed to optimize both UP and PA. This optimization aims to m...
