Abstract:This paper established the simplized algorithm of the gene identification by the curves of the frequency spectrum and noise-signal ratio sequences. We computed the functional relationship between the frequency spectrum and noise-signal ratio of the different Voss mapping and Z-curve mapping and we iterated the noise-signal ratio sequence and got the median of the mean value,then we chose the median value to be the updated threshold,which was the Bootstrap algorithm in statistics.
Keywords:gene identification  noise-signal ratio  Bootstrap algorithm  digital simulation
