    • Hybrid Full-Duplex and Alternate Multiple Relay Selection and Beamforming in AF Cooperative Networks 

      Samara L.; Gouissem A.; Hamila R. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)
      In this paper, multiple relay selection and beamforming techniques are applied to a dual-hop full-duplex (FD) amplify-and-forward relaying network. We show that our proposed techniques allow the selection to be adaptive ...

    • Performance Analysis of Amplify-and-Forward Hybrid Satellite-Terrestrial Networks with Cochannel Interference 

      Yang L.; Hasna , Mazen ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...

    • Relay selection in FDD amplify-and-forward cooperative networks 

      Gouissem A.; Samara L.; Hamila R.; Al-Dhahir N.; Foufou S. ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)
      In this paper, the problems of relay selection and distributed beamforming are investigated for bi-directional dual-hop amplify-and-forward frequency-division duplex cooperative wireless networks. When using individual ...

    • Secure AF Relaying in Power-Constrained UAV Networks 

      Samara, Lutfi; AlAbbasi, Abubakr O.; El Shafie, Ahmed; Hamila, Ridha; Al-Dhahir, Naofal ( IEEE , 2021 , Conference Paper)
      This paper proposes a secure amplify-and-forward (AF) relaying scheme in unmanned aerial vehicle (UAV) networks while accounting for the power consumption limitations of UAVs. Since a UAV's battery life is limited, we ...

    • Wireless transmission using cooperation on demand 

      Hasna, M.O.; Kamel, Tourki; Mohamed Slim, Alouini ( Elsevier B.V. , 2009 , Article)
      Mobile users with single antennas can still take advantage of spatial diversity through repetition based cooperative transmission. In this paper, we consider a scheme in which the cooperation is triggered only if the ...
