| Abstract: | Pointing to the data obtained from semi physical simulation of certain helicopter which mainly has low-frequency noise, a data processing method of depressing and filtering noise from the signal, using the pagoda-structure re constructing arithmetic and the wavelet transform principle, is proposed. The result of simulation shows that the method is practical and efficient on off-line dataprocessing. |
