An adaptive noise reduction method based on singularity value decompose
Zhang Xin-hua · Shengxue jishu · 2008
Based on the principal component analysis(PCA)and singular value decomposition(SVD) denoising, an improved adaptive denoising scheme is proposed. Simulation results and sea trials show that this method can eliminate the noise in the signal more effectively than the classical denoising method based on SVD. Also the waveform is recovered better and the signal-to-noise is increased markedly.
