【摘要】 基于一种通道数为偶数的双正交线性相位完全重构FIR滤波器组的时域设计算法,提出了通道数为奇数的滤波器组设计算法应用的详细过程,并充分利用仿酉滤波器组的性质给出了相应的线性相位完全重构FIR仿酉滤波器组的设计算法,最后讨论了此算法改进并用于两通道长度不尽相等的线性相位完全重构FIR双正交和仿酉滤波器组的设计.更多还原

【Abstract】 By analyzing a time-domain design method of even-channel biorthogonal linear phase PR(Perfect Reconstruction) FIR filter banks,the detailed design process of odd-channel filter banks is given.Then we take advantage of the property of paraunitary filter banks and give the design algorithm.Finally,it is pointed out that the method can also be improved to the design of two-channel unequal biorthogonal and paraunitary linear phase PR FIR filter banks.更多还原
