2L通道复系数FIR仿酉滤波器组的设计

Design of 2L-Channel Complex Paraunitary Filter Banks

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 。

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