自适应滤波方法扣除规则性噪声

本文采用自适应滤波技术,对山东省莒县地震台网记录到的极微震资料中的规则性干扰进行了去噪声处理。结果表明,这种方法不必对噪声进行模式识别,具有简单、快速等优点,在信号与噪声不相关的情况下,可以得到很好的结果。

THE REGULAR NOISE CANCELLING BY ADAPTIVE FILTERING METHOD

In this paper, the adaptive filtering technique has been used to cancel the regular noise in the nanoearthquake date recorded by geosound network in Juxian, Shandong Province. The obtained results indicate that this method has advantages of simple process and fast speed since it doesn't need a model recognition to be carried out to the noise. A satisfactory result can be obtained if there is no correlation between signals and noise.
