Filter Bank Design for Subband Adaptive Microphone Arrays

Abstract

In this paper, the complex (DFT) modulated filter banks is described. Based on the research evidences and findings collected, it mainly focuses on 4 parts: the detailed history of complex (DFT) modulated filter banks part, complex (DFT) modulated filter banks, Matlab programs implementation part and the part of applications in details generally. In order to explain the impact of these aspects on the complex (DFT) modulated filter banks, evidence based on experts’ opinions and identification of facts was used.
