The biorthogonality properties of the multiple vaector-valued wavelet packets in higher dimensions are investigated by virtue of functional analysis methods and Fourier transform, and biorthogonality formulae regarding these wavelet packets are obtained.

• 运用泛函分析方法、傅立叶变换与积分变换，讨论了它们的双正交性，得到关于多元多重向量值小波包的双正交公式。
