A Construction Method of Wavelet with Linear Phase
Zheng Kuang · 哈尔滨工业大学学报：英文版 · 1997
H(ω) |is chosen as a filter for filter H(ω) ,and |H(ω)| is a even function when H(ω) is a real coefficient rational function of e -iω ,and so the scaling and wavelet functions corresponding to | H(ω) | possess linear phases. An algorithm is given for computation of wavelet at very low cost.
