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…
Periodic power spectrum with applications in detection of latent periodicities in DNA sequences
Changchuan Yin, Jiasong Wang
Latent periodic elements in genomes play important roles in genomic functions. Many complex periodic elements in genomes are difficult to be detected by commonly used digital signa…
A Novel Method for Comparative Analysis of DNA Sequences by Ramanujan-Fourier Transform
Changchuan Yin, Xuemeng E. Yin, Jiasong Wang
Alignment-free sequence analysis approaches provide important alternatives over multiple sequence alignment (MSA) in biological sequence analysis because alignment-free approaches…
A Comparative Study of the Signal-to-Noise Ratios of Different Representations for Symbolic Sequences
Jiasong Wang, Chuangyin Dang, Changchuan Yin
Based on the numerical representations by T basic vectors of a symbolic sequence consisting of T symbols, first, we prove mathematical that the total Fourier spectrum of the sequen…
