Next, by the orthogonal multiresolution analysis, the necessary conditions of a kind of M-band band-limited orthogonal wavelet function constructed by the scaling function are proposed.
然后利用正交多分辨率分析，给出由该尺度函数构造的一类频带有限的M进制正交小波函数的必要条件。
The advantage of wavelet packet is because of its two important properties that depend on orthogonality: the scaling function and wavelet are orthogonal over both scale and translation.
使用小波包基函数作为子载波的好处是，它具有两条十分突出的正交性质：相邻(尺度)正交性和平移正交性。
