Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays

In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and Rayleigh fading channels. We also optimize the powers allocated to far and near use...

Summary:In this paper, we derive the Secrecy Outage Probability (SOP) and Strictly Positive Secrecy Capacity (SPSC) of cooperative Non Orthogonal Multiple Access (NOMA) in the presence of K Decode and Forward (DF) relays and Rayleigh fading channels. We also optimize the powers allocated to far and near users to maximize the SPSC or minimize the SOP. Our results are valid for any number of relays with arbitrary positions.
