Abstract:Biorthogonal two-direction wavelet packets with dilation factor are introduced and their properties are discussed by means of the matrix theory and operator theory.A new approach for constructing biorthogonal two-direction wavelet packets is developed.The formulae for performing iteration and decomposition are established.New Riesz bases for L2(R)are obtained by the given biorthogonal two-direction wavelet packets.Finally,an example for constructing biorthogonal two-direction wavelet packets is given.
Keywords:two-direction wavelet  two-direction wavelet packets  two-direction refinable function  biorthogonal
