Use of the Lévy Flight Firefly Algorithm in 2D McClellan Unconstrained Transform Adaptive Filters

Recently published results demonstrated that bio-inspired Lévy Flight Firefly Algorithms (LFFAs) can be effectively applied to IIR adaptive filter structures, non-linear adaptive structures, adaptive filters using second order coupled form sections, and adaptive lattice-ladder structures which have...

Description
Summary:Recently published results demonstrated that bio-inspired Lévy Flight Firefly Algorithms (LFFAs) can be effectively applied to IIR adaptive filter structures, non-linear adaptive structures, adaptive filters using second order coupled form sections, and adaptive lattice-ladder structures which have been well known for many decades. This paper shows how the LFFA can be used in 2D McClellan Unconstrained Transform adaptive filters so the transform domain parameters can be adjusted to accurately approximate the frequency domain contours when no a priori contour information is available. It appears that this is the first time that the LFFA has been used in 2D adaptive filtering.
