摘要：
There are many results in one dimensional wavelet frame theory in recent years. However, since there are some essential differences in high dimensional cases, the classical methods for one dimensional regular wavelet frames are unsuitable for the cases. In this paper, under some conditions on matrix-dilated sequences, a characterization formula for irregular tight frames of matrix-dilated wavelets is developed. It is based on the regular formulation by Chui, Czaja, Maggioni, Weiss, and on the recent multivariate results by Yang and Zhou.
