Abstract

This paper proposes a method for detecting geomagnetic sudden commencement (SC) from a geomagnetic horizontal (H) component by using lifting wavelet filters. Lifting wavelet filters are biorthogonal wavelet filers containing free parameters. Our method is to learn such free parameters based on some training signals which contain the SC. The learnt wavelet filters have the feature of training signals. Applying such wavelet filters to the test signals, we can detect the time when SC phenomena occurred.
