• Joint optimal threshold-based relaying and ML detection in cooperative networks 

      Zeng X.N.; Ghrayeb A.; Hasna , Mazen ( IEEE , 2012 , Article)
      This paper proposes two detection schemes for cooperative networks comprising a source, a relay and a destination. The relay is assumed to operate in a half-duplex mode and it employs decode-and-forward (DF) relaying. The ...
    • Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels 

      Zeng X.N.; Ghrayeb A.; Hasna , Mazen ( Institute of Electrical and Electronics Engineers Inc. , 2012 , Article)
      In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ...
    • User cooperation schemes in the soft handover regions 

      Tourki K.; Alouini M.-S.; Hasna , Mazen ( IEEE , 2009 , Conference Paper)
      This paper examines the effect of relay-assisted soft handover on the performance of the uplink communication in the third generation mobile networks. We focus on users which are traveling over two cell boundaries in a ...
