Multirate Repeating Method for Alias Free Subband Adaptive Filters

摘要

In this paper, we propose the multirate repeat- ing method for alias free subband adaptive filters (AFSAFs) and consider its convergence property. It is shown that we can adjust the convergence speed and the final error of the adaptive filters by varying its two parameters according to the requirements of the applications where the method is applied. The proposed method has two parameters, namely, the number of channel and the number of repetition. We show that by increasing the num- ber for channels we can reduce the final error, and this property is preferred when the signal-to-noise ratio (SNR) is low.
