A Kaiser window approach for designing nonuniform oversampled m-channel filterbanks

This paper shows how the windowing technique based on the use of the Kaiser window can be utilized for designing multiple prototype filters for generalized DFT (GDFT) modulated filterbanks (FBs). Some of the filters in these FBs are used for building a nonuniform M-channel FB. Using the proposed approach results in a simple and fast design algorithm for generating FBs having good overall properties, as is indicated by means of examples.
