Abstract

The definition of the fractional power spectrum and the fractional correlation for random signals are proposed

and the expression of the fractional power spectral density in terms of the fractional correlation function is described.Then

the fractional power spectral relations for the fractional Fourier filter are derived.Finally

the theory obtained is verified by simulations

and indicate the potential applications in chirp signals detection and fractional system identification.
