摘要
综合考察了信号的分析与综合系统 ,即滤波器组合 ;从分解与合成滤波器组合系统构成及其时域和变换域特性出发 ,对滤波器组合加以分类 ,导出有限基上滤波器组合设计的迭代算法 ;并给出不同类型的滤波器组合的参数优化方法 ,扩展了 Daubechies与 Antonini的滤波器系列 ,供信号处理的各种场合选择使用 .
The analysis and synthetic system of signals, i.e., filter bank system, are investigated completely. From the construction of the filter bank system and its features in time-domain and frequency-domain, we classify filter banks, propose the iterative algorithms of filter bank design on finite base, and give the parameter optimization methods for various kinds of filter banks. The filter series of I.Daubechies and M.Antonini are extended for signal processing and application.
