摘要:

基于全相位滤波理论,设计了一种新的FIR窄通带滤波器——APNPBF.它能精确控制通带增益,且不需反复进行参数调试.使用频率采样、Chebyshev窗和全相位窄通带滤波器分别作为蛋白质编码区预测算法的核心,在ALLSEQ和HMR195 2个DNA序列集上获得的碱基层预测准确率AC表明,APNPBF效果优于现有方法.

Abstract:

A novel design of FIR (finite impulse response) filter named APNPBF (all-phase narrow passband filter) was proposed based on all-phase theories. The APNPBF can provide the passband gain with high precision and can satisfy the required specifications without repeatedly modifying the design. The frequency sampling, Chebyshev window and all-phase narrow pass-band filters were applied as the kernel of the prediction algorithm of protein coding regions respectively. The prediction results measured with AC (approximate correlation) at the base level of DNA sequences from data sets HMR195 and ALLSEQ proved the superiority of the proposed method.
