摘要: 本文根據(jù)基于高階統(tǒng)計量辨識非最小相位FIR系統(tǒng)的線性算法之一遞歸封閉型算法,提出了一種利用非線性最小二乘解的優(yōu)化迭代方法提高參數(shù)估計精度的改進算法,最后還給出了仿真實例。Abstract: 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.
