| 摘 要： | 本文分析表明:目前使用的线性差分方程增阶时的参数递推算法并不精确成立,其误差随模型阶的增加和样本长度的减小而增大。为此,本文推出线性差分模型增阶时参数的精确递推算法,并对计算量进行了讨论。

| Abstract: | This paper analyzes and shows that the current recursive algorithm is not so positively true when the parameters of a higher linear order difference model are computed by using lower order parameters,and its error will increase with the increase of the model order and the decrease of the sample length. Therefore this paper presents an exact recursive algorithm of linear dilference model parameters in order increasing and discusses the quantity of computation in detail. |
