摘要
本文利用DFT滤波器组、ZFFT,提出了一种宽带信号的实时谱分析方法。有效地解决了宽带信号高分辨率 谱分析要求的大运算量与实时性之间的矛盾。理论分析与计算机仿真表明该算法切实可行、有效并且易于实现。
In this paper, by using DFT filter bank and ZFFT, we present an algorithm of spectrum analysis for the wide band signal .we solved effectively the contradiction between the great arithmetic demand of high resolution spectrum analysis and real time demand. Theoretical analysis and computer simulation indicate that the method is practical, effective and easily achieved.
