Amplify-and-Forward Relaying Based Spectrum Sharing in Both Time and Spectrum Domains With Wireless Powered Primary User

open access: yesIEEE Access, 2019
We propose a spectral and energy efficient cooperative spectrum sharing scheme with the primary user (PU) capable of harvesting wireless energy. Along with an access point (AP) transferring wireless power to PU, a secondary source (SS) and a secondary ...

Including Diversity Through Cooperation

open access: yesProcedia Computer Science, 2012
AbstractIn this article we describe the experience of several Portuguese Higher Education Institutions (HEI) that in the midst of a legislative void regarding the inclusion of students with special education's needs, try to work their way into the inclusion of those students through cooperation.We will focus on how that cooperation came into being, the

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 ...

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
