摘　　要：正交小波变换可归结为滤波器组的分析和设计,进而便于VLSI的实现。文中将正交格形滤波器用于实现滤波器组结构内部的正交小波变换,并提出了在独立参数空间中,每个参数仅用一个正交μ-循环逼近的格形滤波器结构,它简单、有效。The orthogonal wavelet transform can be summed up as analysis and design of the filter bank structure,which makes it convenient for VLSI implementation In this paper,orthogonal lattice filters are used to implement orthogonal wavelet transforms within a filter bank structure An approximate lattice filter structure using only one orthogonal μ rotation per parameter in an independent parameter space is presented,which is simple but efficient for VLSI realization
