本文考虑了基于加权平方误差准则线性相位FIR数字滤波器的设计问题，提出一种随机抽样递推最小二乘（RS－RLS）设计方法．将设计问题看成一个线性系统的辨识问题，辨识参数所需的数据由一随机抽样法产生，辨识算法采用递推最小二乘法上RS-RLS设计法简单易用，设计范例说明这一方法具有很高的设计精度．
In this paper, the design of linear phase FIR digital filter based on weighted square error criterion is considered. A stochastic sampled recursive least squares (RS-RLS) design method is proposed. Considering the design problem as a linear system identification problem, the data needed to identify the parameters are generated by a random sampling method. The recognition algorithm is reusable by the RS-RLS method. The design example shows that this method has High design accuracy.
