Fixed-point algorithm for independent component analysis with reference
|
Abstract:
Independent component analysis with reference which utilized a prior information of the original signals as reference signals only achieve the expected source signals extraction and eliminate the uncertainty of the traditional independent component analysis,by taking the closeness measure of the expected signal and reference signal as the contrast function,proposed a new fixed point algorithm.Avoided the step size and provided a better initial value to accelerate the convergence. Computer simulations with s...
