Abstract—In this paper, wavelet packet algorithm was used in the de-noising of underwater acoustic signal processing since wavelet packet algorithm is suitable for non-stationary signal processing. The principle of wavelet packet de-noising algorithm was described and the MSE of underwater acoustic was improved by means of wavelet packet de-noising greatly.The result of computer simulation by Matlab illustrates that de-noising algorithm is an effective signal preprocessing method.
