| 摘 要： | 研究了RLS(递推最小二乘)自适应滤波器和小波消噪方法的滤波特性,在仿真的基础上选取两者作为实际采集信号的消噪处理方法。为了取得较好的消噪效果,对不同类型的信号采用不同的处理方法,对于特定的信号可采用将两者相结合的方法。处理结果表明,所选用的方法消噪效果明显。

| Abstract: | The characteristics of recursive least-squares adaptive filter and wavelet threshold de-noising method were introduced. Based on the simulation, those method were utilized to process the real sampling signal. In order to get better results, the different types of data were proccessed by different ways. To special type of signal, the combination of two methods was adopted. The results show that those methods perform well. |
