摘要
本文根据基于高阶统计量辨识非最小相位FIR系统的线性算法之一——递归封闭型算法,提出了一种利用非线性最小二乘解的优化迭代方法提高参数估计精度的改进算法,最后还给出了仿真实例。
An improved algorithm which is based on the recursive closed-form algorithm for non-minimum phase FIR system identification via higher order statistics is presented. In order to increase the parameter estimation accuracy, the improved algorithm uses the optimal iterative method for nonlinear least-square solition. Finally the simulation examples are also given.
