Adaptive modulation has been widely adopted by some newly developed wireless packet networks such as WCDMA HSDPA (Wideband Code Division Multi-Access High Speed Downlink Packet Access) and HiperLAN/2
etc.With careful consideration on the attribute of link bandwidth uneven distribution with time slots in the adaptive modulation system
here a novel packet scheduling algorithm
Adaptive Differentiated Compensation Fair Queuing
is proposed.In this algorithm.An analytical scheme based on workload is used
and several sub-queues are involved.It can provide QoS guarantee to all backlogged flows
fair residual bandwidth sharing
and rational compensation mechanism to conquer the burst error in wireless environments.Besides the algorithm
in order to simulate the adaptive modulation system
a new channel model based on multi-state Markov chain is proposed in this paper.
