Characterizations of Tight Frame Wavelets with Special Dilation Matrices

الملخص EN

We study all generalized low-pass filters and tight frame wavelets with special dilation matrix M (M-TFW), where M satisfies Md=2Id and generates the checkerboard lattice.

Firstly, we study the pseudoscaling function, generalized low-pass filters and multiresolution analysis tight frame wavelets with dilation matrix M (MRA M-TFW), and also give some important characterizations about them.

Then, we characterize all M-TFW by showing precisely their corresponding dimension functions which are nonnegative integer valued.

Finally, we also show that an M-TFW arises from our MRA construction if and only if the dimension of a particular linear space is either zero or one.
