Adaptive Rate-Scheduling with Reactive Delay Control for Next Generation CDMA Wireless Mobile Systems
2006
EURASIP Journal on Wireless Communications and Networking
Preserved Fulltext
It is an adaptive rate scheduler over multiclass CDMA systems with predictive adaptation control to adapt to nonstationary loadings; and feedback-enhanced reactive adaptation control to counteract arrival ...
To minimize QoS degradations during nonstationary packet loadings, predictive rate schedulers adapt the operation according to anticipated packet arrival rates deduced via specified estimation algorithm ...
Feedback control unit monitors average delays of each class and if it detects that a class is degraded (possibly because of estimation errors) it corrects the problem in order to achieve efficient resource ...
