Because vanishing moments are important in wavelets and applications,this paper constructs two Hermite spline waveletsψ1(x) andψ2(x) with compact supports on[-2,2].They have vanishing moments of order 6 and 7 respectively,as well as symmetric and antisymmentric properties.In addition,it is proved that the integer translations of wavelets are L2((?)) stable.All these work are motivated by Jia's paper.Firstly,we show that all symmetric and antisymmetric wavelets with compact supports on[-1,1]are essentially the wavelets given by Jia in some sense; Secondly,we try to find wavelets with vanishing moments of higher order and compact supports on[-2,2],according to Jia's standard.However,the stability of the integer translations is a problem.Finally,we receive the desired result by changing the standard.
