Wavelet Denoising and Its Application in the Data-processing of some Helicopter Semi-physical Simulation

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 data-processing.
