Abstract: “We used the higher orders spectra to improve observability of the coding regions. Smoothened spectrograms of the second and sixth orders were received. Efficiency of the proposed method for protein coding regions was estimated on 8000 samplings of DNA C. elegans F56F11.4. We used signal-to-noise ratio to evaluate the accuracy of the measures in predicting the coding regions.”

Keywords: autoregressive models, DNA sequence, spectrogram, power spectrum density
