Effects of CSI Knowledge on Secrecy of Threshold-Selection Decode-and-Forward Relaying
IEEE Access, 2017 This paper considers secrecy of a three node cooperative wireless system in the presence of a passive eavesdropper. The threshold-selection decode-and-forward relay is considered, which can decode the source message correctly only if a predefined signal ...

Optimal Multi-Antenna Transmission for the Cooperative Non-Orthogonal Multiple-Access System
Applied Sciences, 2021 We investigate the beamforming for the multi antenna cooperative non-orthogonal multiple access (NOMA) system, where an access point (AP) delivers messages for multiple user terminals (UT) with successive interference cancellation (SIC) reception method.

Cooperative Non-Orthogonal Multiple Access for Beyond 5G Networks
IEEE Open Journal of the Communications Society, 2021 In the beyond 5G networks, extraordinary demands for data rates and capacity are to be met. A possible candidate to address these challenges is Non-Orthogonal Multiple Access (NOMA) technique, which leads to higher diversity gains and massive ...

Cooperative Diversity in a Spectrum Sharing Environment [PDF]
Journal of information and communication convergence engineering, 2011 In this paper, we investigate cooperative diversity in a spectrum sharing environment where secondary users utilize primary users’ spectrum only if the interference power received at the primary users is maintained below a predetermined level. The outage probability of a selective decode-and-forward (DF) based cooperative diversity scheme in the ...

Performance of selection relaying and cooperative diversity [PDF]
IEEE Transactions on Wireless Communications, 2009 In this paper, a two-hop cooperative multi-relay communication network is considered. Selection relaying schemes are attracting considerable attention due to their prudent bandwidth utilization and ability to provide full diversity. The recent developments in selection relaying (SR) have largely focused on information theoretic analyses such as outage ...
