Abstract EN
This paper presents, a new algorithm for designing Quadrature Mirrors Filters (QMF) banks using windowing techniques.
In the proposed algorithm the cutoff frequency of the prototype filters is iteratively varied such that the perfect reconstruction at frequency (ω = 0.5π) in ideal condition is approximately equal to 0.707.
The designed QMF banks are used as mother for speech compression algorithm based on discrete wavelet transform.
The evaluation tests prove the efficiency of the proposed algorithm in speech compression using wavelets.
The comparison results between the proposed algorithms with other existing algorithms used for designing QMF banks show an important reduction in reconstruction error and number of iterations.
