Parameterization of 4-Band Orthogonal Scaling Filters with Linear Phase

该文得到了具有线性相位的4带正交尺度滤波器的参数化形式,同时给出了构造相应的小波滤波器的一个简单的构造方法.应用所给出的参数化形式,得到了具有紧支撑的对称正交的尺度函数,进而也获得了相应的小波.

In this paper, the authors give parameterization of 4-band orthogonal scaling filters with linear phase, and propose a simple method to construct the corresponding wavelet filters. Applying this parameterization form, the authors can derive symmetric orthogonal scaling functions with compact support. Furthermore, the corresponding wavelets can be obtained by the method.
