摘要
为了在应用中能更灵活地选择所需要的小波,研究了一类依赖于某参数的加细函数和相应小波的性质,揭示了这类小波在参数取不同的值时相应小波的联系和区别,即这类小波均具有紧支撑性和正交性,而它们的光滑性却不完全相同.
In order to select the required wavelets more flexibly, we investigate the properties of some refinable functions and wavelets that depend on a certain parameter, and reveal their internal relations and differences between the corresponding wavelets to the different parameter values. Namely, this class of wavelets all have compact support and orthogonality while their regularity is not entirely the same.
