变模态分解在微地震信号去噪中的应用

摘要

本文介绍了一种完全非递归的变模态分解方法，它可以将有用的输入信号分解成离散数量的子信号（模式）。使用该方法对模拟信号和实际微地震资料进行信号去噪处理，取得了良好的效果。%This paper introduces a kind of completely non-recursive mode decomposition method,which can decompose the input signal into the discrete number of sub-signal(mode).Good results have been achieved when it is applied in denoising process of analog signals and real seismic data.
