从完全重构滤波器组出发，分析了小波与滤波器组之间的关系，讨论了复数离散正交小波的构造。
Starting from perfect reconstruction filter Banks, the relationship between the wavelet and the filter Banks is analyzed, and the construction of complex discrete orthonormal wavelet is discussed.
并进一步构造了与尺度函数对称点一致、系数长度不超过8的所有对称（反对称） 小波滤波器组。
Moreover, all symmetric and antisymmetric wavelets, which have same symmetric point as the scaling function and the length of their filters are no more than 8, are also given.
