wavelet packet basis meaning in Chinese

小波包基

Signal denoising algorithm and its application based on best wavelet packet basis
基于最优小波包基的信号去噪算法及其应用
The method directly executes wavelet packet decomposition of handwriting texture using wavelet packet basis db6 at scaling 3 in 2d space , then reconstructs the decomposition coefficient of 15 wavelet packet best basis which are took by shannon entropy cost function
该方法直接在二维空间上由db6小波包基对笔迹纹理实施3尺度小波包分解，再在由以香农熵为代价函数提取得到的15个小波包最好基处对分解系数实行重构。
This article shows a new method to construct symmetric compacted orthogonal wavelet packet basis ： the original compacted orthogonal wavelet basis and scaling function are decomposed into symmetric and anti - symmetric parts respectively ， then we prove that three of four parts is also wavelet basis and another is scale function . we find it simple to process 1 - d signal . finally , by these results above , all the results above are applied to dsp
本文提出一种新的对称化方法，把一大类紧支集实值的非对称正交小波函数分解成对称和反对称两部分，并证明了其相应的两部分仍然构成对称和反对称的紧支正交小波基，而且我们发现尺度函数对称和反对称部分分别是某子空间的尺度函数和小波函数。
