Reduction of noise in flaw signals based on independent component analysis
HU Lang-tao · Journal of Hefei University of Technology · 2007
The basic theory of independent component analysis(ICA),which is a new processing method of array signals,and the fixed-point algorithm for ICA are briefly introduced.A fixed-point algorithm for ICA is used to reduce the noise in flaw signals.Denoising simulation experiment is carried out,and the presented method is compared with a traditional digital filter.The results show that in the denoising application the ICA algorithm is superior to the traditional digital filter.Thus the fixed-point algorithm for ICA has large potential in denoising of flaw signals.
