论文摘要
这项工作的目的是设计完美重建和奇数系数（甚至订单）的FIR QMF（正交镜面过滤器）过滤器的设计。根据设计，这些过滤器将具有线性相和整数延迟。这些过滤器对在小波变换和其他多频分解中有许多应用。从很久以前就研究了完美的重建过滤器，但我们仍然找到了有关它们的出版物。
The purpose of this work is the design of FIR QMF (Quadrature Mirror Filters) filters of perfect reconstruction and odd number of coefficients (even order). By design, these filters will have linear phase and integer delay. These filter pairs have many applications in wavelet transforms and other multi-frequency decompositions. Perfect reconstruction filters have been studied from long time ago but we still found publications about them.
