Abstract
By incorporating the acoustic emission with fast Mallat arithmetic, the noise in acoustic emission signal can be greatly decreased. The theory is illustrated, which use the wavelet transform based Mallat arithmetic to deal with the noise filtering and signal decomposing and reconstructing. Also it is testified that the wavelet transform based Mallat arithmetic is good at the acoustic emission signal noise-decrasing.
