無完全重構(gòu)約束的兩通道自適應FIR濾波器組設(shè)計

Design of Two-Channel Signal-Adapted FIR Filterbanks without Perfect Reconstruction Constraints

  • 摘要: 該文研究了在無完全重構(gòu)約束情況下兩通道自適應FIR無混疊濾波器組的時域設(shè)計方法。由于放松了對完全重構(gòu)的約束，子帶編碼器的失真由系統(tǒng)失真和量化失真兩部分構(gòu)成。在整體比特數(shù)和輸入過程給定的情況下，本文通過優(yōu)化濾波器系數(shù)，使得子帶編碼器的整體失真達到最小，實現(xiàn)提高其編碼增益的目的。后面的設(shè)計實例驗證了該方法的有效性。
    Abstract: This paper investigates the time-domain design method of two-channel signal-adapted FIR alias-free filterbanks without Perfect Reconstruction (PR) constraints. For subband coders based on filterbanks without PR constraints, the total distortion is composed of two parts: the systemic distortion and quantization distortion. For a given total bit budget, the minimization of the total distortion is an unconstrained nonlinear programming. Due to its high nonlinearity, the design results greatly depend on selection of initial filterbanks. Two approaches to select the initial filterbanks, the associated algorithm and designs of several examples are given in this paper. The obtained signal-adapted filterbanks achieve larger subband coding gains than the existing methods, which verifies our method is effective.
