    • An Adaptive Transmission Scheme for Two-Way Relaying with Asymmetric Data Rates 

      Zhang, Xuehua; Hasna, Mazen O.; Ghrayeb, Ali ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)
      In this paper, we address the problem of asymmetric data rates in two-way communication systems. In particular, we propose an adaptive transmission scheme that combines network coding (NC) and opportunistic user selection ...

    • End-to-end performance of transmission systems with relays over Rayleigh-fading channels 

      Hasna , Mazen; Alouini M.-S. ( IEEE , 2003 , Article)
      End-to-end performance of two-hops wireless communication systems with nonregenerative relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and applying some new closed-form expressions ...

    • Relay assignment in multiple source-destination cooperative networks with limited feedback 

      Zhang, X.; Jafarkhani, H.; Ghrayeb, A.; Hasna, M.O. ( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)
      We consider in this paper relay assignment for cooperative systems with mutiple source-destination pairs. The objective here is to assign relays to the source-destination pairs in such a way that all pairs achieve the ...

    • 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 ...
