Noise Reduction of Oil Prospecting Signal Based on Dyadic Wavelet Transform Modulus Maximum

摘要：

The algorithm of discrete dyadic wavelet transform and the theory of noise-removing based on modulus maxima are introduced by the paper. The conjugate gradient algorithm is presented detailedly. At last, the simulation noisy signal, synthetic seismic signal and practical seismic data are all processed using the method based on modulus maxima of dyadic wavelet transform. The results manifest that the algorithm remove noise effectively, and make the quality of seismic data advance greatly.
