In some adaptive filtering applications, some researchers have explored the use of the multirate technique to improve the performance of the adaptive algorithms. However, some of these approaches have shown a degradation in performance. In this paper, we consider the conditions for filter banks which enable us to avoid the degradation. Next, we propose a filter bank with frequency sampling filters, and its performance is compared to those of conventional filter banks for adaptive system identification.
