    • Inter-relay interference management schemes for wireless multi-user decode-and-forward relay networks 

      Omri A.; Hasna , Mazen; Letaief K.B. ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for wireless multi-user decode-and-forward (DF) relay networks. The schemes are based on a DF half-duplex ...

    • Prior zero forcing for cognitive relaying 

      Song S.H.; Hasna , Mazen; Letaief K.B. ( IEEE , 2013 , Article)
      Relaying primary signals by cognitive base-stations (CBSs) can help the primary system and thus win CBSs a higher chance to transmit their own signals. For this purpose, conventional zero-forcing (CZF) beamforming is a ...

    • Priority-based zero-forcing in spectrum sharing cognitive systems 

      Hamdi K.; Hasna , Mazen; Ghrayeb A.; Letaief K.B. ( IEEE , 2013 , Article)
      We consider a spectrum sharing scenario between cognitive radio (CR) users and a licensed primary user (PU), in which the PU is not able to successfully transmit data to its destined receiver. The cognitive base station ...
