摘要
道路信号是一种复杂的含有多种成分的时域波形,不仅具有非平稳性,同时信号中还存在各种干扰和噪声。本文针对小波分析的特点,结合信号去噪方面的要求,对非平稳信号的噪声消除进行了研究。通过Matlab对基于小波分析的道路信号消噪进行了仿真,显示了小波在信号去噪方面良好的应用效果。
The signals collected directly from the road are very complicated in the time domain, which have non-stationary and contain many kinds of components, and there are various disturbances and noises in them. Combined with requirements of the signal denoising and characteristics of Wavelet Transforms, non-stationary signals noise separation is investi- gated in the paper. Simulate the road signals denoising procedures by Wavelet analysis with the tool of Matlab, and the results show the good effect of signals in wavelet denoising.
