摘要

本文提出一种新的信号估计方法──小波变换，理论与仿真结果证明，在短数据信号情况下，基于小波变换的谱估计方法其分辨率要高于ＦＦＴ方法．文中详细讨论了小波的谱估计算法，并给出了双正弦信号的仿真结果．

Abstract

In this paper a new signal estimating method-wavelet transformation is given. It’s also proved by theoretical and emulation that spectrum estimation based on wavelet transformation has better distinguishing rate than that of FFT. It also discussed the algorithm of spectrum estimating

the dual-sine emulative result is given at last.
