摘要

本文分析了一种用于平稳输入的子带自适应数字滤波器(ADF)。首先，用滤波器组的多相矩阵和未知系统的多相矩阵重新表示子带自适应滤波方案。在此基础上研究了带交叉项的子带ADF。然后，对传统子带ADF进行了最优子带滤波器和时间平均均方误差的频域处理。这些表示使我们能够很容易地看到子带自适应滤波中的混叠效果。

Statistical analysis of subband adaptive filters

This paper presents an analysis of subband adaptive digital filters (ADF) for a stationary input. First, the subband adaptive filtering scheme is reexpressed by the polyphase matrices of the filter bank and the unknown system. Based on this structure the subband ADF with cross terms is studied. Then, for the conventional subband ADF, the optimal subband filters and the time-averaged mean-squared error are treated in the frequency domain. These representations enable us to easily see the aliasing effects in subband adaptive filtering.
