Fractional Fourier Transform Overview by sujit kumar das is a document available to read on EtoBox.
The fractional Fourier transform (FRFT) generalizes the classical Fourier transform and can be interpreted as a rotation in the time-frequency plane. An FRFT with an angle of π/2 corresponds to the classical Fourier transform, while an angle of 0 corresponds to the identity operator. The FRFT of a signal expresses it in terms of an orthonormal basis of chirps. The paper explores relationships between the FRFT and time-frequency representations like the Wigner distribution, ambiguity function, short-time Fou
