Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
Zaghdoud N.; Mnaouer A.B.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)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 ... -
Secrecy performance analysis of half/full duplex AF/DF relaying in NOMA systems over κ−μ fading channels
Zaghdoud N.; Mnaouer A.B.; Boujemaa H.; Touati F. ( Springer , 2022 , Article)Although the progress in understanding 5G and beyond techniques such as Non-Orthogonal Multiple Access (NOMA) and full-duplex techniques has been overwhelming, still analyzing the security aspects of such systems under ... -
Secrecy Performance Analysis of Multi-Antenna NOMA System with AF/DF relaying under External and Internal Eavesdropping Scenarios
Zaghdoud N.; Mnaouer A.B.; Alouane W.H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Due to the successive interference cancellation (SIC) technique, Non orthogonal multiple Access (NOMA) users have the capability of decoding the other paired users sharing the same resource bloc. As a result, NOMA technique ... -
Secrecy performance of AF relaying in cooperative NOMA over rician channel
Zaghdoud N.; Alouane W.H.; Boujemaa H.; Mnaouer A.B.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)In this paper, we investigate the secrecy performance of an Amplify-and-Forward (AF) relay in a cooperative NOMA system. The AF relay ensures the transmission of the signal in the presence of one passive eavesdropper where ... -
Secrecy Performance of Cooperative NOMA System with Multiple Full-Duplex Relays against Non-Colluding/Colluding Eavesdroppers
Zaghdoud N.; Mnaouer A.B.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)In 5G and beyond wireless communication net-works, non-orthogonal multiple access (NOMA) and Full-Duplex (FD) techniques are considered as promising key techniques. However, the secrecy in NOMA systems has proven to be ... -
Secure Performance Analysis for Full-Duplex Cooperative NOMA System in the Presence of Multiple Eavesdroppers
Zaghdoud N.; Mnaouer A.B.; Alouane W.H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)This paper investigates the physical layer security of a full-duplex (FD) Decode-and-Forward (DF) NOMA network assumed to undergo independent and identically distributed Nakagami-m fading. Herein, we provide a secrecy ... -
Secure Performance of AF and DF Relaying in Cooperative Noma Systems
Zaghdoud N.; Alouane W.H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)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 ... -
Secure Performance of DF Relaying in Cooperative NOMA over Rician Fading Channels
Zaghdoud N.; Mnaouer A.B.; Alouane W.H.; Boujemaa H.; Touati F. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)In this paper, a Decode-and-Forward (DF) relaying system for Non Orthogonal Multiple Access (NOMA) networks is considered, where the transmitted information between the relay and NOMA users can be overheard by an eavesdropper. ...
