Effects of CSI Knowledge on Secrecy of Threshold-Selection Decode-and-Forward Relaying

open access: yesIEEE 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 ...

Cooperative Non-Orthogonal Multiple Access for Beyond 5G Networks

open access: yesIEEE 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 ...

Responsible Research and Innovation & Digital Inclusiveness during Covid-19 Crisis in the Human Brain Project (HBP)

open access: yesJournal of Responsible Technology, 2020
Covid-19 changes the lives for all of us: Institutions and other places are closed; it is not possible to see friends and family personally and keeping distance is the topmost commandment. Therefore, most of us are working from home and digitalisation is

Cooperative Diversity in a Spectrum Sharing Environment [PDF]

open access: yesJournal 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 ...

Optimal Multi-Antenna Transmission for the Cooperative Non-Orthogonal Multiple-Access System

open access: yesApplied 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.

Performance of selection relaying and cooperative diversity [PDF]

open access: yesIEEE 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 ...

Multipoint-to-Multipoint Cooperative Multiuser SIM Free-Space Optical Communication: A Signal-Space Diversity Approach

open access: yesIEEE Access, 2020
In this paper, a novel signal-space diversity (SSD) technique based multipoint-to-multipoint cooperative scheme for a multiuser free-space optical communication system is proposed.

Distributed Cooperative Relaying Based on Space-Time Block Code: System Description and Measurement Campaign

open access: yesIEEE Access, 2021
In cooperative relaying, intermediate stations are required to enhance the end-to-end transmission performance. The performance of the cooperative relaying scheme has been investigated theoretically and via computer simulations.
