Abstract-In the research of elastic wave signal detecti on algorithm, a method based on adaptive wavelet analysis and segmentation thres hold processing of the channel noise removal methods is suggested to overcome th e effect of noise, which is produced by absorption loss, scattering loss, reflec tion loss and multi-path effect during the elastic wave in the transmission und erground. The method helps to realize extraction and recovery of weak signal of elastic wave from the multi-path channel, and simulation study is carried out a bout wavelet de-noising effects of the elastic wave and obtained satisfactory r esults.
Key words-through-the-earth communications of elastic wave; weak signal detection; adaptive wavelet analysis
