Abstract
Filtering is an important part of signal processing.In view of the characteristics of blind signal processing(BSS),the traditional filtering technology is not suitable for blind source separation directly.However,as a pre-processing technique,filtering is necessary to use in the separation of independent components.This paper proposed an adaptive filtering method for BSS.Meanwhile,it also gave a judgment method for the threshold of filtering.Then,it proposed the algorithm of adaptive filtering for BSS.With this method,it could solve the problem arise by using low pass and high pass filtering for blind signal processing.The simulation results show that this method not only can find out the outliers components in the observed data effectively,but also do not destroy the statistical characteristics of the data.Further,it can avoid the poor performance that the independent component algorithm use higher order statistics.关键词
