摘要 该文通过证明 TDAC余弦调制滤波器组时域和频域分析的 PR条件的等价性,建立了 TDAC和 CMF分析技术的内在联系。并针对音频信号处理中往往根据人耳听觉的临界子带特性对信号进行非等带宽滤波,运用已有的一种 CMF非等带宽余弦调制滤波器组构造技术构造了一个 TDAC非等带宽余弦调制滤波器组。 Cosine Modulated Filter(CMF) bank is a kind of broadly used filter bank. By proving the equivalence of the Perfect Reconstruction(PR) conditions of time-analysis and frequency-analysis, the inherent relationship between Time Domain Aliasing Cancellation(TDAC) and CMF is found. By the means, the useful results of the two methods can be conveniently. Finally, a new kind of nonuniform filter bank is built based on TDAC which can be easily modified to audio coding in accord with psychoacoustics.
