小波分析在汽车降噪中的应用

Application of Wavelet Analysis in Vehicle Noise Reduction

研究了以小波分析法为理论基础的小波降噪技术在汽车中的应用,对含噪信号同时进行时域和频域处理,即对信号进行分解、组合和重构。然后用MATLAB进行仿真,通过对仿真结果的分析,验证了小波降噪技术在汽车中应用的可行性。

The application of wavelet denoising technology based on wavelet analysis in automobile is studied. The technology can process noisy signals in both time and frequency domains, that is, decompose, combine and reconstruct the signals. Then the simulation is carried out by using the software of matlab, and the feasibility of the application of wavelet denoising technology in automobile is verified by the analysis of the simulation results.
