Optimal design of Weighted Least Square based fractional delay FIR filter using Genetic Algorithm

Abstract

In this paper, a Weighted Least Square based designing of fractional delay FIR filter using Genetic Algorithm is proposed. In this method, Genetic Algorithm is implemented to evaluate the closed form error function. This helps in speeding up the process of filter design and achieving globally optimized final solution. Three design examples are given to illustrate the results of proposed approach. These examples demonstrate the effectiveness of proposed approach as compared to the existing filter design methods.
