摘要
首先介绍一类品质因素可控的基于波－（实和复）Ｙ－母波，然后用两种方法分析研究Ｙ－母波的正交条件．理论分析和数值计算结果表明：对于复Ｙ－母波，不可能存在正交的整数平移基，而对于实Ｙ－母波，却存在正交的和几乎正交的整数平移基．
A novel class of analytic mother wavelet-(complex and real) Y-wavelet is introduced,and then two ways, by which investigate the orthogonal and almost orthogonal condtions of complex and real Y-wavelets are presented.Theoretical analysis and results of numerical solution show that. It impossible to construct an inte gral translation orthogonal basis by using complex Y-wavelet,Ohly for the real Y-wavelet might exist the case of integral translation orthogonal basis.
