| Abstract: | The basic theory of wavelet package and the specific steps was introduced.Aiming at the time-changing character of signal,the improved double trees algorithm was applied to choose the optimum wavelet package in order to reduce noise with adaptive character.The result of adaptive algorithm was compared with the result of tradition algorithm through numerical simulation.And the result showed that the adaptive algorithm can restrain the noise better. |
