小波变换与傅立叶变换在信号消噪中的对比研究
Research of the difference of the wavelet transform and the Fourier transform in decreasing the noise
【摘要】 本文介绍了小波变换,阐述了小波消噪的原理。通过仿真,比较了二者在信号消噪方面的优缺点,得到了小波变换在信号消噪方面明显优于傅立叶变换的后记。
【Abstract】 Taking the advantage of the wavelet transform’s better time-frequency characteristic, we can decrease the unwanted noise effectively The results of the emulation represents that the wavelet transform is superior to the Fourier transform.
