In view of mode mixing caused by EMD(Empirical Mode Decomposition),this paper proposed a self-similarity traffic prediction method based on the combination models.Through the EEMD(Ensemble Empirical Mode Decomposition) process,the long-term dependence existing in network traffic was removed effectively.Additionally,according to the different characteristics of each IMF(Intrinsic Mode Function) produced by EEMD,ANN(Artificial Neural Network) and ARMA(Auto Regressive Moving Average) were adopted for different IMFs.The simulation results demonstrate that the proposed method can effectively predict the traffic and has high precision.

目前宽带卫星通信系统广泛采用了多点波束及星上交换技术,但大都仅提供固定业务或便携式业务,如何在这种体制下实现"动中通"业务相关的研究还比较少.本文主要介绍了Spaceway3系统针对"动中通"应用的设计理念,可作为以后其他系统设计的参考.
