Quadrature mirror filter bank design based on hybrid bee colony technique

This paper proposed a modified evolutionary technique formed by the hybridization of bee colony and Nelder–Mead Simplex search to optimize coefficients Quadrature Mirror Filter (QMF). The performance QMF can be evaluated in terms error pass-band, stop-band measure ripple. A objective function is designed this work, expressed as weighted sum errors minimized using technique. results obtained from are compared with previously reported optimization techniques based on design. significant improvement various attributes has been attained earlier bank design techniques.
