An Adaptive Playout Algorithm Based on Kernel Estimation

摘要：

Adaptive playout algorithms play a very important role in guaranteeing the QoS (Quality of Service) in VoIP (Voice over IP). The prediction of network delay in adaptive playout algorithms is essentially a time series analysis problem. Currently most delay predition methods are based on parameter estimation. However, the strong parameter assumptions in parameter estimation usually could not correspond to the actual situation, which leads to poor performances. This paper proposes a new adaptive playout algorithm based on kernel estimation which is a type of nonparameter estimation. Simulation results show that the algorithm can adapt to the changeful network environment and reduce the loss and delay significantly.
