| Abstract: | Improved genetic quantum algorithm (IGQA) is used to design FIR digital filters. Samples in transitions of filters are optimized, which solves the problem that values obtained by look-up table method (LTUM) are not optimums. Aiming at prematureness appearing easily when GQA is used to optimize continuous functions with many peaks, IGQA is proposed.The results of testing typical function and designing FIR digital filters demonstrate that IGQA is better than GQA and other GAs because IGQA has faster convergent speed and better global search capability, and IGQA can overcome premature phenomenon effectively. The performances of filters designed by IGQA are better than that of LTUM. |
