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 ...
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 ...
