摘要

本文研究了一种有效的迭代加权最小二乘(IRLS)算法，用于设计LP逼近FIR滤波器。最优滤波器系数是通过迭代求解一个线性方程组得到的，该方程组的相关矩阵可以进一步简化为封闭表达式，并在给定滤波器时进行预计算。仿真结果表明，该算法性能优良，复杂度为0 (N2)。

Efficient weighted L/sub P/ algorithm for the design of low-pass FIR filters with some closed-form derivations

In this paper, an efficient iterative reweighted least-squares (IRLS) algorithm for the design of LP approximation FIR filters is investigated. The optimal filter coefficients are obtained by iteratively solving a system of linear equations whose associated matrix can be further simplified as closed-form expressions and pre-calculated as the filter is specified. Simulation results indicate the excellent performance of the proposed algorithm has a complexity of O(N2)
