利用遗传算法的数字成形滤波器设计方法
Designed method of digital shaping filter using genetic algorithm
摘要
Abstract
Digital shaping filters are important part of digital baseband communication systems. It is designed for limiting the spectrum of signal with introducing Inter Symbol Interference(ISI)as little as possible. Traditional way to design fil-ters can be divided into two steps:Estimating the orders and computing the ripple coefficient. However, current methods for estimating the orders are only available for Finite Impulse Response(FIR)filters. They are not available for digital shaping filters, a special kind of FIR. In order to solve this problem, an algorithm which combines the two steps of designing digital filters is proposed. The experiments show that the proposed algorithm can get better results in estimating the or-ders and computing the ripple coefficient.关键词
