摘要
Mutual Information can be used to measure the similarity of the autocorrelation function and the Information, this paper take the mutual information as the object function for signal separation, iterative the cyclic correlation matrix of the mixed signal by the natural gradient search for the optimization to find the mutual information of separated signals to recover the source signal. The simulation resulation results proved that the new algorithm can separate the mixed signals effectively.
