Denoising Method for Vibrating System of Fiber Grating Based on Wavelet Singular Value Decomposition

摘要：

Aiming at the deficiency of wavelet threshold denoising for vibrated signal of non-uniform noise distribution, a method based on Singular Value Decomposition and wavelet threshold de-noising is presented.The matrix with vibrated signal and signal of non-uniform noise is made by rapture method, and the non-uniform noise is decomposed averagely into several orthogonal subspaces by singular value decomposition.The signal which is rebuilt by the subspace with maximal singular value is de-noised with wavelet threshold de-noising method.The results show that the proposed method, compared with wavelet threshold denoising is an efficient tool to extract useful component with less distortion.
