The Problem of Power Spectrum and the Signal-To-Noise Ratio and Its Fast Algorithm Implementation in Gene Identification

Chun Yan, Xiu-juan Su, Xin-min LIU, Jia Song


This paper studies the gene identification model, which adopted the signal processing and analysis method to find the problem of power spectrum and the signal-to-noise ratio and its fast algorithm implementation of the gene coding sequence. Since Discrete Fourier transform algorithm has large computation, according to the principle that the far distance between the bases lead to a small interrelation in the power spectrum calculation and by descending to reduce the time complexity of the algorithm. We use 3-cyclical interception DNA fragment to structure a N/3 point to realize fast calculation of DNA sequence of power spectrum. The computer simulation results showed that the improved algorithm not only enhances the recognition effect of the first exon, but also reduces the time complexity of the original algorithm greatly.
