摘要

自适应调制无线系统的带宽随时隙不均匀分布(BUDTS)特性破坏了传统流量调度算法中带宽随时隙均匀分布的隐含假设。因此，需要适合这种情况的新方案。提出了一种新的自适应差分补偿公平排队算法(ADCFQ)，为所有积压流提供基本的QoS要求和公平的剩余带宽共享，并为由于突发信道错误而导致的滞后流提供补偿机制。仿真结果表明，在ADCFQ中很好地考虑了带宽分布不均匀的影响。

A novel scheduling algorithm for IP traffic in adaptive modulation system

One property, bandwidth uneven distributed with time slots (BUDTS) in the adaptive modulation wireless system destroys an implicit assumption of traditional traffic scheduling algorithm that the bandwidth is evenly distributed with time slots. Therefore, new scheme fit for such circumstance is needed. We propose a novel algorithm, named adaptive differentiated compensation fair queuing (ADCFQ), to provide basic QoS requirement and fair residual bandwidth sharing to all backlogged flows, as well as the compensation mechanism to the lagged flows due to burst channel error. Simulation shows that in ADCFQ, the effect of uneven bandwidth distribution is well considered.
