Aimed at widespread application of fractional Fourier transform in engineering and technology, the concepts of fractional Fourier transform and fractional multidiemension-multi-resolution analysis are introduced in this article. The methods for construction of fractional multiresolution analysis are investigated with time-frequency analysis, functional analysis, and fractional Fourier transform: The fractional multidimension-multiresolution analysis is characterized, also. The existence conditions of the fractional multidimensional function are given out at the end.
