提出了非最小相位线性时不变（NMP-LTI） FIR系统辨识的递推和最小二乘方法。该方法利用FIR系统输出的二阶和三阶累积量，该系统的输入是一个独立的、同分布的（i.i.d）非高斯过程。由于系统阶数的知识对许多系统识别算法至关重要，因此本文还提出了仅使用输出累积量来确定FIR系统阶数的新方法。为了说明该方法的有效性，给出了各种仿真实例。>
Recursive and least squares methods for identification of non-minimum-phase linear time-invariant (NMP-LTI) FIR systems are developed. The methods utilize the second- and third-order cumulants of the output of the FIR system whose input is an independent, identically distributed (i.i.d.) non-Gaussian process. Since knowledge of the system order is of utmost importance to many system identification algorithms, new procedures for determining the order of an FIR system using only the output cumulants are also presented. To illustrate the effectiveness of the methods, various simulation examples are presented. >
