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。 Based on the recursive closed-form algorithm, one of the linear algorithms for identifying non-minimum phase FIR systems based on higher-order statistics, this paper proposes an improved algorithm to improve the accuracy of parameter estimation by using the optimization iterative method of nonlinear least squares solution. Finally, A simulation example is given.
