Construction of Wavelet Bases with Vanishing Movement
-
摘要: 在N≥2情况下构造了一种性质良好的小波母函数,这种小波母函数N阶可导并且趋于零的阶数为O|t|-N(|t|→∞),同时具有N-2阶消失矩和某种对称性.文章还就N=4的情况给出了计算实例.Abstract: A kind of mother wavelet with good properties is constructed for any N≥2, which is di-f ferentiable for N times, converges to zero at the order of O|t|-N(|t|→∞) and has N-2 order of vanishing movement and some property of symmetry meanwhile. A computation example for N=4 is also given.
