摘要
本文通过构造小波对应的滤波器,从理论上给出一种构造所有二进紧支撑复小波的方法,从而解决了一类支撑在整数段上的紧支撑小波的构造问题,并具体给出了支撑长度为3的小波所对应的滤波器.
In this paper, on the condition of the elements of filter (or coefficients of muhiresolution equation) being complex numbers, a method to construct all filters of binary complex wavelets with compact supports is given.
