Abstract :
Two well known optimization algorithms, the genetic algorithm (GA) and the simulated annealing algorithm (SAA), are investigated for IIR adaptive phase equalizers. For non-convex error surfaces, gradient-based algorithms often fail to find the global optimum. This work compares the ability of the GA and the SAA to achieve the global minimum solution for multi-order all-pass adaptive filters to be used for the phase equalization of minimum phase SAW filters.
