变模态分解在微地震信号去噪中的应用

Application of variational mode decomposition in denoising for microseismic signal

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.
