摘要
多重小波是近年来新兴的小波研究方向,它具有许多一维小波所不具备的优越性质.完全正交的多重小波在构造上有很大的难度。
Multiwavelets are the newest direction of wavelets research. They have some good properties that scalar wavelets have not. The construction of completely orthogonal multiwavelets is very difficult, so in many application people can use biorthogonal multiwavelets as analysing tool. This note gives a method to construct biorthogonal multiscaling functions from multiscaling functions, and give an example by using this method.
