| 摘 要： | 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．

| Abstract: | This paper considers the design problem of linear-phase FIR digital filters withweighted least-squares error criterion and a random sampling recursive least-squares (RS-RLS)algorithm. The design problem is regarded as parameter estimation for a supposed linear systemwhose parameters are those of the filter to be designed. These parameters are estimated with recursive least-squares (RLS) algorithm. Input signals of the supposed system are generated with arandom sampling(RS)method. The proposed RS-RLS algorithm is very simple and easy to use. A'simulation example demonstrating the effectiveness of the proposed algorithm is provided. |
