A parallel tabu search algorithm for digital filter design

Purpose – The purpose of the paper is to present a novel design method for the optimal finite word length (FWL) finite impulse response (FIR) filters.Design/methodology/approach – The design method is based on a parallel tabu search (TS) algorithm which uses the crossover operator of the genetic algorithm.Findings – Three design examples have been presented to show that the proposed method can provide a good solution to the design problem of a FWL FIR filter. In order to show the validity of the proposed method, the performance of the suggested method has been compared to those of widely‐used other methods. From the comparison results, it was concluded that the proposed method can be efficiently used for the optimal FWL FIR filter design.Research limitations/implications – The number of examples can be increased and also the performance of the proposed method might be compared to other design methods, apart from those presented in this work, developed for the design of optimal FWL FIR filters.Practical im...
