摘要
现实生活中存在大量非平稳随机振动干扰信号,将它们从有用信号中滤除具有十分重要的意义。介绍自适应信号的处理方法及其在抑制振动信号中的应用,并采用自适应噪声对消处理的方法对振动干扰进行对消处理。用MATLAB进行仿真验证的结果表明:自适应噪声对消在处理因振动干扰而产生的非平稳随机信号时,具有可行性,消噪效果较好。
The paper deals with the adaptive signal processing method and its application in the suppression of the vibration signal .The adaptive noise cancellation processing method is designed as the vibration noise cancellation means. The simulation confirmation with MATLAB was carried out. The result indicates that there is feasibility for the adaptive noise cancellation to deal with non-steady random signal caused by vibration disturbance and the denoising effect is good.
