摘要/Abstract

摘要： 针对处理复值信号的需要,给出了一种偶数通道复系数FIR仿酉滤波器组的设计方法,应用该方法得到的滤波器具有近似线性相位的特点,因此,在多带滤波中引入较小的相位失真。

Abstract: An algorithm is proposed for paraunitary filter bankswith complex impulse response to meet with the processing of complex signal. The filters designed by the algorithm have nearly linear phase response. Thus, thedistortions aren't introduced in the phase spectrum.

Key words: digital filter, paraunitary filterbanks, multirate signal processing
