A novel efficient and enhanced combinational window family is proposed for developing the
prototype filter for a two-channel quadrature mirror filter bank, where the gradient-based …

In the design of hearing aids (HA), the real-time speech-enhancement is done. The digital
hearing aids should provide high signal-to-noise ratio, gain improvement and should …

In this chapter, four important wavelet families are discussed: the Daubechies wavelet
family, the Coiflet wavelet family, the Morlet wavelet family, and the biorthogonal wavelet …

In this paper, a uniform cosine modulated filter bank (CMFB) is designed using the
Incremental Ant Colony Optimization with Local Search (IACO R-LS) and utilized for the …

An iterative technique is proposed to optimally design the two-channel linear phase (LP) FIR
quadrature mirror filter bank (2c-LP-FIR-QMFB). In each iteration, first, the frequency-domain …

Among the theory and design of oversampled nonuniform filter banks (NUFBs), most of the
existing works only consider the cases with integer decimators, and up to now the issue with …

Purpose: Amplitude and aliasing errors inherently occur in designing of M-channel cosine
modulated filter banks. In this study, it is aimed to present a new design method for M …

This work presents a new Electrocardiogram (ECG) data compression technique based on
the optimum two channel quadrature mirror filter (QMF) bank. Firstly, prototype filter is …

Bu tez çalışmasında, etkin bir sezgisel algoritma olan yapay arı koloni (Artificial Bee Colony,
ABC) algoritması, modifiye ABC (mABC) ve hızlı ABC (qABC) algoritmaları ile parçacık sürü …
