Abstract

The fractional Fourier transform (FRFT) is a unified time-frequency transform that does not suffer from the cross terms and is suitable for processing the non stationary signal. It is required to define the corresponding analysis range and discrete resolution in the FRFT domain in order to apply the FRFT to digital signal processing field. In this paper the analysis range and resolution of the discrete FRFT are obtained according to the relationship between the Wigner distribution and the FRFT
