The concept of fusingenergy cost function and method based on the function are proposed, the method was used for the recognition of underwater acoustic signal.
提出了融合能量代价函数的概念及基于代价函数的小波包能量法，并将其应用于水声信号的识别。

The new arithmetic constructed the best wavelet packet based on the wavelet library with the criterion of fusingenergy cost function and contract the most valuable features of the signals.
