摘要

帕克斯-麦克莱伦算法(1973)是非常流行的设计FIR数字滤波器。它基于一种叫做Remez交换的线性规划算法。我们的新算法是基于二次规划的,其中包括线性规划作为一个特例。本文中的滤波器允许设计者控制峰值误差和总平方误差之间的权衡。这些滤波器是根据峰值约束最小二乘(PCLS)最优性准则设计的。

New quadratic programming algorithms for designing FIR digital filters
The Parks-McClellan algorithm (1973) is very popular for designing FIR digital filters. It is based on a linear programming algorithm called the Remez exchange. Our new algorithm is based on quadratic programming, which includes linear programming as a special case. The filters in this paper permit the designer to control the tradeoff between the peak error and the total squared error. These filters are designed according to the peak-constrained least-squares (PCLS) optimality criterion.<>
