Application of a Comprehensive One Dimensional Wavelet Threshold Denoising Algorithm in Blasting Signal

When collecting blasting signal, the blasting signal is inevitably mixed with a certain noise signal, and the noise signal will affect the analysis of the blasting seismic wave, and it is not conducive to formulate corresponding measures. The blasting signals are periodically and changeable, the previous denoising methods are not totally fit to blasting signals, sometimes the original signals are regarded as noise signal and are being removed. In this paper, a new algorithm combine the soft and hard threshold function is introduced and the Simulation experiments and results analysis show that it can not only effectively remove the noise signals, but also save the details of the blasting signals.
