The method of detecting SESs in TCD has attracted notice recently as an effective method for short-term earthquake prediction. However, since most of the TCD collected in Japan is affected by train noise, therefore detecting SESs in TCD itself is considered as an extremely arduous job. The goal of our research is to obtain a method for detecting SESs, which is difficult because of train noises. The SES and train noise are considered as independent source signal.
