A novel algorithm to get the Fourier power spectra of a real sequence
Jiasong Wang, Changchuan Yin
For a real sequence of length of m = nl, we may deduce its congruence derivative sequence with length of l. The discrete Fourier transform of original sequence can be calculated by…

A Fast Algorithm for Computing the Fourier Spectrum of a Fractional Period
Jiasong Wang, Changchuan Yin
The Fourier spectrum at a fractional period is often examined when extracting features from biological sequences and time series. It reflects the inner information structure of the…
