Biorthogonal Multiwavelet Packets with Scale=a
Jin Leng · Gongcheng shuxue xuebao · 2001
The frequency field can be divided into tinier ones with the emerging of wavelet packets. It can enlarge the appearance of high frequence. A method for the construction of biorthogonal multiwavelets with scale=a is composed according to the studying of biorthogonal multiwavelets with scale=a. They are more flexible in its application. And for the same biorthogonal multywavelet, varied biorthogonal multiwavelet packets can be constructed by using this methed. The biorthogonal character of biorthogonal multiwavelet packets is studied and the formula of their decomposing is composed emphatically like as two scale biorthogonal single wavelet packets.
