Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3594610
.... Improving the signal-to-noise ratio of seismic data is the primary task of seismic data processing. In practical research, many algorithms for suppressing random noise interference are proposed. In order to achieve better seismic data denoising technology, this paper introduces a new algorithm: fast K-SVD...

Finally, under the constraint of the signal-to-noise ratio of seismic data, time-varying frequency division deconvolution is implemented on the high SNR frequency segment. The broadband and high-resolution seismic data can to obtain. The model test and actual data application show...

... of high signal-to-noise ratio (SNR). It underestimates the error for small SNR. ZZB utilizes a priori information and, hence, provides a more sound result for noisy data. Both CRB and ZZB require a knowledge of the spectral variance of the signal that is often hard to determine in seismic experiments...
