【摘要】 首先给出了三角样条函数及其性质,然后在此基础上给出了一种构造三角样条小波的新方法.该方法简单易行,而且构造出的小波具有许多良好的性质,如对称性(具有线性相位或广义线性相位)、良好的时频局部特性、短支集及半正交性等,这些对信号处理是非常重要的.更多还原

【Abstract】 This paper presents a new kind of trigonometric spline wavelets on the interval on the basis of tirgonometric spline functions.The method is very simple and easy,and that these wavelets possess many good properties such as symmetry and anti-symmetry(linear phases or generalized linear phases),good time-frequency locality,short support,semi-orthogonal.更多还原
