基于進行計算設(shè)計無法的完全重構(gòu)兩通道濾波器組

Design of sopot two-channel perfect reconstruction fir filter banks based on evolutionary strategies

  • 摘要: 該文提出了一種設(shè)計無乘法完全重構(gòu)的兩通道濾波器組的方法。這種濾波器組在基于對提升模式結(jié)構(gòu)改進的研究成果之上,提出了給定初始值的進化計算搜索設(shè)計方法。這種設(shè)計方法具有比用遺傳算法快的特點。文中詳細描述了此算法的過程,并給出了設(shè)計例子和結(jié)果。
    Abstract: This paper proposes a method based on evolutionary strategies (ES) for design ofmultiplier-less two-channel perfect-reconstruction (PR) filter banks (FB). The filter banks are jbased on the modified lifting scheme structure. A new ES given a seed is proposed to find the *sum of power-of-two (SOPOT) coefficient of the filter bank. This method requires much less 玠esign time than genetic algorithm. Finally, a PR FB with SOPOT coefficient is given as an :example to illustrate the proposed method.
