| 摘 要： | 对于已知小波函数，它的性能是确定的。为了改进它的某些性能，文章从一给定双正交小波出发，利用提升框架构造满足特定要求的双正交、紧支撑小波，结合Mallat算法，得出快速算法，并给出了具体例子进行说明。

| Abstract: | The properties of a wavelet function are fixed.In order to improve the property,this pa-per begins with the given birorthogonal wavelets and then constructs compactly supported and biorthogonal wavelets by the lifting scheme.The fast algorithm is made combined with the Mallat algorithm.Moreover,several examples are given to demonstrate the idea. |

| Keywords: | birorthogonal wavelets lifting scheme filter multi-resolution analysis |
