Application and Simulation of Wavelet Packet Transform in Underwater Acoustic Signal De-noising

摘要：

　　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.
