The Application of Dyadic Wavelets Transform Modulus Maximum in the Seismic Signal De-noising

Abstract. This article first briefly introduces the characteristic of the wavelets transform ,explains the concrete operations process that the conjugate gradient method restructuring signal, then narrates in detail the modulus maximum value de-noising's algorithm, finally using the dyadic wavelet transform modulus maximum value de-noising method respectively carries the processing on the synthesis and noisy signal and the actual seismic signal, the experimental result indicates that this algorithm makes the good progress, the seismic data quality is enhanced greatly
