The Optimum Wavelet Base of Wavelet Analysis in Coal Rock Microseismic Signals
Coal rock rupture microseismic signal is characterized by time-varying, nonstationary, unpredictability, and transient property. Wavelet transform is an important method in microseismic signals processing. However, different wavelet bases yield different results when analyzing the same signal. To st...
