从Haar尺度函数入手
提出尺度系数函数概念
引入时移因子
将Battle-Lemarié子波基拓展而构造出广义Battle-Lemarié多分辨分析基.然后从理论上论证这种拓展的合理性与广义Battle-Lemarié基的一些基本性质.研究结果表明:所有广义Battle-Lemarié基继承了(原始)Battle-Lemarié基的许多优点
比如标准正交性
时、频局域化特征和指数衰减性等
同时还得到一系列新的对称基
广义Battle-Lemarié基的正则性优于相应的(原始)Battle-Lemarié基.
Starting with investigating the Haar scaling function
the scaling coefficient function is first presented.Then the Battle-Lemarié basis is extended to the generalized Battle-Lemarié basis by introducing time-shift factor to the scaling coefficient function of the Battle-Lemarié.The rationality of the extending method
which is used in this paper
is theoretically proved.Some basic properties of the generalized Battle-Lemarié basis are also discussed.Our research results show that all the Battle-Lemarié bases inherit many good properties of the original Battle-Lemarié bases
such as orthonormality
time frequency localization
exponential decay and so on.Meanwhile a series of neoteric symmetric multiresolution analysis basis are generated.The generalized Battle-Lemarié wavelets are better than the corresponding original Battle-Lemarié wavelets in regularity.
