一种只用高阶累量进行MA系统辨识的线性方法

A New Linear method for MA system Identification Using Higher Order Statistics (HOS) only

本文给出了只用高阶累量进行系统辨识的线性公式，运用这组公式进行MA系统辨识时，由于只用到高阶累量，所以对高斯噪声不敏感．我们将本方法与其它线性方法作了比较，并进行了模拟实验，结果表明这种方法效果很好。

In this paper we derive a group of new general linear equations equations for MA system identification . Using these equations , we present a linear method for MA system identification and prove that this method leads to a unique solution . Because higher order statistics (cumulents) are used only our mothods are insensitive to any additive Gaussian noise . Also we have compared our method to other linear equation methods , and simulation results thow our method's good performance
