A design method for oversampled warped cosine-modulated filter banks
Maxim Vashkevich, A. Petrovsky · 2010
This paper presents an efficient method for the design of M-channel oversampled warped cosine-modulated filter banks. The method consists in filter prototype design for synthesis filter bank using optimization procedure, which minimizes filter bank overall distortion transfer function. Optimization takes into account channel subsampling factors as well.
