Power interference removal method based on independent component analysis
基于独立分量分析的工频干扰消除技术

This paper studied the fundamentals and fast algorithm of ICA, tried to remove the power interference in seismic data on the base of analyzing the features of seismic data and the power interference. Compared with the results of the conventional methods, ICA has good effect on removing the power interference and can protect the available signals effectively. Results show that ICA has better effect on improving the signal to noise ratio and has a good application perspective.
