Jl. Li et al., A SIMPLE DESIGN METHOD FOR NEAR-PERFECT-RECONSTRUCTION NONUNIFORM FILTER BANKS, IEEE transactions on signal processing, 45(8), 1997, pp. 2105-2109
In this correspondence, we propose a simple design method for nonunifo
rm integer-decimated filter banks based on a uniform cosine-modulated
filter bank, The resulting distortion and aliasing are comparable to t
he stopband attenuation of the prototype filter. Examples are given to
demonstrate the proposed method.
