A Review of Polyphase Filter Banks and Their Application

Abstract

In this report we review and compare numbers of different filter bank approaches which include discrete Fourier transform (DFT) filter bank, modified discrete Fourier transform (MDFT) filter bank, and cosine modulated filter bank. Our simulation results show that there is no one best overall method that gives the best performance. One method can perform better than others under one scenario, but not as well as others under different scenarios. Given a particular situation or specific application, the best method in terms of reconstruction and dealing with channel distortion may vary.
