Secure Performance of AF and DF Relaying in Cooperative Noma Systems

Nesrine Zaghdoud, Wided Hadj Alouane, Hatem Boujemâa +1 more

In this paper, we study the secrecy outage probability (SOP)and the strictly positive secrecy capacity (SPSC)of cooperative non-orthogonal multiple access (NOMA)system with a single antenna over Rayleigh fading channel in which there are a source, a relay node, two destinations and one eavesdropper. The relay adopts amplify-and-forward (AF)and decode-and-forward (DF)relaying schemes. The SOP and SPSC performance are analyzed to evaluate the level of security granted to legitimate users for both AF and DF protocols. The effects of the optimal power allocation value on system performance are also discussed and provided through numerical results.

Physical layer security for cooperative NOMA networks via Nakagami-m fading channels

Wided Hadj Alouane

Abstract In this paper, we investigate the physical layer security in cooperative non-orthogonal multiple access (NOMA) networks over Nakagamim fading channels. Both amplify-and-forward (AF) and decode-and-forward (DF) protocols are studied. More particularly, closed-form exact and asymptotic expressions for strictly positive secrecy capacity are provided considering NOMA-AF and NOMA-DF relaying systems. Numerical results are presented to justify the accuracy of the obtained theoretical analysis. These results show that NOMA-AF and NOMA-DF relaying networks have a similar secrecy performance.

Physical Layer Security for Cooperative NOMA Systems

Jianchao Chen, Liang Yang, Mohamed‐Slim Alouini

In this correspondence, we investigate the physical layer security for cooperative nonorthogonal multiple access (NOMA) systems, where both amplify-and-forward (AF) and decode-and-forward (DF) protocols are considered. More specifically, some analytical expressions are derived for secrecy outage probability (SOP) and strictly positive secrecy capacity. Results show that AF and DF almost achieve the same secrecy performance. Moreover, asymptotic results demonstrate that the SOP tends to a constant at high signal-to-noise ratio. Finally, our results show that the secrecy performance of considered NOMA systems is independent of the channel conditions between the relay and the poor user.
