查询词典 GATA

Fast Fourior Transform plays an important roll in digital signal processing,its the kernel algorithm in a lot of process for signal processing.this paper first summarizes many algorithm for Fast Fourior Transform that in common use and synthesizes many reasons to adopt the radix-2 Demation-in-Frequency algorithm,then it compares two ways of implementing digital signal processing,the two ways are in field-programmable gata array and in programmable digital signal processor respectively.it points out the advantage and disadvantage of two ways.

快速傅立叶变换是数字信号处理中的重要内容之一，是很多信号处理过程中的核心算法。本文先总结了快速傅立叶变换的一些常用算法，并综合种种因素，采用了基2按频率抽取算法作为实现算法，然后将以现场可编程门阵列和以DSP处理器这两种实现数字信号处理的方式进行了比较，指出了各自的优点和不足之处。
