摘要

本文将系统地考察多通道滤波器组合

定义一大类非奇异多通道滤波器组合

导出正规型多通道滤波器组合的分析、合成与传递方程;讨论其归一化、平滑度与对称性的优化约束;特别地提出基于零谱矩阶数的优化方法以提高滤波器在通带与阻带的平滑度

即所谓零谱矩滤波器;给出对称多通道滤波器组合及其设计示例

供信号处理各领域使用.

Abstract

Multi-channel filter bank (MFB) is investigated systematically.A kind of nonsingular multi-channel filter banks (NMFB) is defined.The analysis equations

synthesis equations and transfer equations of NMFB are introduced.And the optimizing restrictions for normalizing

smoothing and symmetry of filters are discussed.Particularly

the concept of zero spectrum moment filters to optimize filter's character is proposed.At last the design procedure and example of symmetric multi-channel filter bank are given.
