Research on Sparse Denoising of Strong Earthquakes Early Warning Based on MEMS Accelerometers
In view of the fact that the noise in the same frequency band as the useful signal in the MEMS acceleration sensor observation data cannot be effectively removed by traditional filtering methods, a denoising method for strong earthquake signals based on the theory of sparse representation and compre...
