De-noising of spectral signal based on stationary wavelet transform

Abstract

In order to effectively alleviate the effect of noise in spectral signal, stationary wavelet is applied to process the spectral signal in this paper. The simulation result of stationary wavelet transform and classic wavelet transform on wheat canoy and rice canoy respectively show that both wavelet are effective in alleviating the effects of noise, while stationary wavelet gets a better SNR and reserves character of signal.
