介绍了自回归滑动平均模型。基于二阶统计量和高阶统计量,研究了两种ARMA模型建模方法。阐述了两种ARMA模型在信号处理中的不同应用范围。
The autoregressive moving average model is introduced. Based on second-order statistics and high-order statistics, two ARMA modeling methods are studied. The different applications of the two ARMA models in signal processing are described.
