A simple algorithm for gene prediction with improved noise suppression

A simple algorithm to improvise the identification of protein coding regions in DNA sequences by period-3 property is presented. Background noise present in the period-3 DNA spectrum has been captured using DFT and notch filter. Elimination of this noise from the DNA spectrum improvised the detection of protein coding regions. Algorithm is data independent as it does not requires the empirical determination of any parameter for increasing the discrimination between coding and non-coding regions of a DNA sequence. An improvement in the global accuracy over the DFT and recently reported boosting approach is observed.
