A Selecting Method of Wavelet Packet Bases
Youqian Feng · Journal of Air Force Engineering University · 2005
Wavelet packet library contains many wavelet packet bases, which can handle the different components of signal. Therefore, by selecting suitable bases, the effective features of signal can be extracted. Based on divergence criterion and genetic algorithm, a method of selecting the best base is presented. The experiments using the sound signals of four kinds of aircraft are performed and the result demonstrates that the method is effective and feasible.
