Adaptive Threshold De-noising Algorithm of Roll Eccentricity Signal
To solve the problem of roll eccentricity signal with the noise in the HAGC system,a new method based on adaptive threshold de-noising algorithm of roll eccentricity signal is proposed.The new method can self-adaptively decide the threshold of wavelet analysis and make the SNR as a function of the parameter of the filter to acquire the optimal threshold parameter by using midpoint method.This method has the properties of self-adaptation,strong robustness,low calculation,simple arithmetic and so on.Simulation shows that the result of de-noising with this new method is much better than soft-thresholding algorithm and hard-thresholding algorithm and has a good de-noising result for roll eccentricity signal in HAGC system.
