关 键 词：impulsive noises wavelet transform shift invariant 

摘      要：Donnoho et have proposed a method for de-noising by threshold,which has been used in many signal de-noising and compression *** the method of Dohono is not successful for impulsive *** have proposed a method,which detect and wipe off impulse noise,then de-noising by shift-invariant *** results indicate that:it can better detect and reduce the impulsive noise and it can reduce the noise while keeping the signal edges better compared to other wavelet based denoising algorithms.
