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