Precoding-Aided Spatial Modulation for the Wiretap Channel with Relay Selection and Cooperative Jamming
( Hindawi Limited , 2018 , Article)We propose in this paper a physical-layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ... -
Relay assignment in network-coded cooperative systems with M-PSK modulation over asymmetric channels
( IEEE , 2010 , Conference Paper)We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ... -
Secrecy Performance Analysis of Cooperative NOMA system with multiple DF Relays
( 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
( 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 ... -
Secure DoF for the MIMO MAC: The case of knowing eavesdropper's channel statistics only
( Institute of Electrical and Electronics Engineers Inc. , 2019 , Conference Paper)Physical layer security has attracted research attention as a means to achieve secure communication without the need for complicated upper layer encryption techniques. The secure degrees of freedom (SDoF) of various networks ... -
Secure Performance of DF Relaying in Cooperative NOMA over Rician Fading Channels
( 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. ... -
Throughput of a cooperative energy harvesting secondary user in cognitive radio networks
( Wiley Blackwell , 2016 , Article)This paper investigates the maximum throughput of a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU). The SU is assumed to be an energy harvesting node, which harvests energy packets from the ...
