摘要 阐述了独立成分分析(Independent Components Analysis,ICA)的基本原理,将快速ICA(FastICA)算法应用于消除地震信号中的工频干扰,对输出信号的相关系数绝对值进行对比.结果表明:与传统的工频干扰消除技术相比,FastICA算法可以更加有效地消除微信号中的工频干扰. The fundamentals of independent component analysis (ICA) is elaborated. The FastICA algorithm is applied to eliminating the power interference of seismic signal, the absolute values of correlation coefficient of the output signals are compared. The simulation results show that compared with the traditional power interference eliminating techniques, the FastICA algorithm can be more effective in removing the power interference of micro-signals.
