Abstract: Aiming at the problem of separating exploding seismic signal from natural seismic signal, an empirical-period based mode cell filtering (EP-MCF) method is introduced. A novel EP-MCF-based method for separating the exploding seismic signal is proposed. The experimental results show that this method can separate exploding seismic signal from nature seismic signal efficiently. This paper provides a novel method for seismic signal analysis.

Key words: vibration and wave, mode cell filtering, natural seismic signal, exploder seismic signal
