Query: Practical design of multi-channel oversampled warped cosine-modulated
  filter banks   A practical approach to optimal design of multichannel oversampled warped
cosine-modulated filter banks (CMFB) is proposed. Warped CMFB is obtained by
allpass transformation of uniform CMFB. The paper addresses the problems of
minimization amplitude distortion and suppression of aliasing components
emerged due to oversampling of filter bank channel signals. Proposed
optimization-based design considerably reduces distortions of overall filter
bank transfer function taking into account channel subsampling ratios.
Matlab-implementation of the proposed warped CMFB design method is available in
public GitHub repository.
