    • Adaptive modulation in multi-user cognitive radio networks over fading channels 

      Foukalas, F.; Khattab, T.; Poor, H. Vincent ( IEEE Computer Society , 2013 , Conference Paper)
      In this paper, the performance of adaptive modulation in multi-user cognitive radio networks over fading channels is analyzed. Multi-user diversity is considered for opportunistic user selection among multiple secondary ...

    • Antenna subset selection at multi-antenna relay with adaptive modulation 

      Choi, Seyeong; Hasna, Mazen O.; Yang, Hong-Chuan; Alouini, Mohamed-Slim ( John Wiley & Sons, Ltd. , 2013 , Article)
      In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities ...

    • Comparison of relaying strategies for cooperative diversity systems with adaptive modulation 

      Choi, Seyeong; Alouini, M.-S.; Yang, Hong-Chuan; Hasna, M.O. ( IEEE , 2009 , Conference Paper)
      In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ...
