Title: Signal Processing of Earthquake Precursor at ELF Band
Abstract: In this paper, the signal processing technology of EM precursors for predicting earthquakes is discussed. The observed signals contain local signals related to earthquakes as well as global background noise which is stronger than the local signals. A method of global noise elimination by independent component analysis (ICA) is discussed. The second signal processing is to extract the sign of anomaly relevant to earthquake prediction. For the processing, the linear predicting coefficient (LPC) method is applied. The LPC error is well acknowledged as a precursor of large earthquakes exceeding magnitude seven
