A novel method for designing near-perfect reconstruction oversampled nonuniform cosine-
modulated filter banks is proposed, which combines frequency warping and subband …

The allpass transformation of higher order is a very general concept to construct a frequency
warped analysis-synthesis filter bank (AS FB) with nonuniform time-frequency resolution. In …

A novel numerical design approach for allpass transformed DFT filter-banks with
subsampling is proposed. Such frequency warped filter-banks possess a non-uniform time …

Two novel computationally efficient implementations for 3-D FIR cone filters are proposed in
this paper. In the proposed implementations, the well-known 1-D quadrature mirror cosine …

Allpass transformed filter banks provide a nonuniform frequency resolution and can be used
in mobile speech processing systems, eg, cellular phones or digital hearing aids. The …

A new approach to nonuniform filter bank design is introduced. The designed filter bank is
composed of many different uniform sections which are joined together by transition filters …

The allpass transformation is a common approach to design a frequency warped analysis-
synthesis filter-bank (AS FB) with non-uniform time-frequency resolution. Such filter-banks …

The allpass transformation of multiple order is a very general approach to design a
frequency warped analysis-synthesis filter-bank (AS FB) with non-uniform timefrequency …

This paper presents a method for designing low-delay nonuniform pseudo QMF banks. The
method is motivated by the work of Li, Nguyen and Tantaratana, in which the nonuniform …

This thesis presents a novel subband noise reduction technique for speech enhancement,
termed as Adaptive Subband Wiener Filtering (ASWF), based on a criticalband gammatone …
