2007 IEEE 18th International Symposium on Personal, Indoor and …, 2007•ieeexplore.ieee.orgThis paper investigates the power minimization problem in OFDMA based wireless multihop
systems with the knowledge of channel state information (CSI). The joint allocation problem
is divided into two stages: bandwidth allocation and subchannel assignment. Efficient
optimal and suboptimal algorithms for both stages are jointed together to provide beneficial
and stable improvements by exploiting a form of multiuser diversity via intelligent
subchannel partitioning on the frequency-selective fading channel.
