Abstract :
This paper presents an analysis of a subband adaptive filter structure using noncausal Wiener filter theory and multirate system concepts. The transfer function of the overall system is close to that of the full band optimal Wiener filter whereas that of the conventional subband filter contains a delay of the filter bank
