A new denoising method based on combining multi-scale product with wavelet shrinkage is presented. The wavelet coefficients used in the method are extracted by histogram of adjacent wavelet coefficients product. The new denoising method not only preserves signal's original features, but also has stronger ability to remove noise. The numerical experiments show that the proposed method can significantly raise SNR, decrease MSE and preserve the shape of signal better than the original wavelet shrinkage...

提出一种将相邻尺度的小波系数乘积与小波阈值收缩相结合的信号去噪方法.该方法采用小波系数乘积的直方图方法提取小波系数.用该方法去噪既能很好地保持信号突变点的原有特性,又具有较强的去噪能力.数值仿真表明,与小波阈值收缩方法相比,该方法在信噪比和均方差指标上都有明显的提高,并能很好地保持信号的形状.

This paper researches the relationship between index of road surface evenness of mean square deviation and the ride quality of vehicle. It shows that better index of road surface evenness doesn,t mean a good ride quality although the ride quality is in proportional to the road evenness normally. Only if the wave length of the road surface is beyond to the people,s sensitive wave length range, a better road surface evenness means a better ride quality.

在研究路面平整度均方差指标与路面状态之定量关系的基础上,结合车辆在路面上行驶时所产生的振动对人体所产生的影响,分析研究了路面平整度均方差指标与行车舒适性之间的关系,得出平整度指标与行车舒适性之间具有一定关系,但是平整度指标的高低并不能完全代表行车舒适性的优劣。
