Firstly, the definition of biorthogonal multi-wavelet packet corresponding to multiple multi-resolution analysis, the oretical 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.
