我们证明了分数阶Hilbert变换保持了双正交小波的性质。对于一个自然生成的双正交小波对构造从一个给定的双正交尺度对,我们提出了一种设计,构造一个更好的双正交尺度对的自然生成的双正交小波对使用分数希尔伯特变换。我们还提出了一种计算方法的低通和高通滤波器。
We show that the fractional Hilbert transform preserves the biorthogonal wavelet property. For a naturally generated biorthogonal wavelet pair constructed from a given biorthogonal scaling pair, we propose a design to construct a better biorthogonal scaling pair for the naturally generated biorthogonal wavelet pair using the fractional Hilbert transform. We also propose a calculation method for low-pass and high-pass filters.
