首先，给出了对应于多重多分辨分析的双正交多小波包的定义，建立了具有任意矩阵伸缩的双正交多小波包的理论框架.在此基础上，给出了具有有任意矩阵伸缩的高维不可分双正交多小波包的构造方法.由此构造的多小波包的分分解系数能从不同的滤波器中抽取，这使的小波包的应用更灵活.

-Firstly, the definition of biorthogonal multi-wavelet packet corresponding to multiple multi-resolution analysis, the theoretical framework of biorthogonal multiwavelets with arbitrary dilation matrix package. On this basis, has the arbitrary matrix scalable, high-dimensional nonseparable biorthogonal multiwavelet packet structure thus constructed wavelet packet sub-decomposition coefficients from the different filters to extract more flexible, which makes the application of the wavelet packet.
