非平稳信号的快速傅里叶变换与小波分析的比较

The Differences of Between Analyzing by Fast Fourier Translation and Analyzing by Wavelet

在对通信系统信号进行分析时,非平稳信号是经常遇到的。采用快速傅里叶变换和小波变换对通信系统信号进行分析,比较了分析结果,证明小波分析更适合于突发信号的分析。最后给出了Matlab实验结果。

The unbalanced signal is common in communication signal analysis. The paper applies FFT and wavelet to analyze the unbalanced signal, then makes a comparison between the two methods.
