We discuss Independent Component Analysis as one of the most popular and robust techniques to decompose mixed signals. ICA has 

In the model, the data variables are assumed to be linear mixtures of some unknown latent Ten spatial infomax ICA decompositions were performed on two fMRI data sets collected from the same subject. The maximallyindependent spatial components were then tested across decompositions for one-to-one correspondences. Matching independent component maps by mutual information alone proved ineffective. Matching component map pairs by correlating their z-transformed voxel map weights To characterize the magnitude of this ICA uncertainty and to understand the extent to which it may influence findings within ERP and EEG investigations, ICA decompositions of EEG data from 32 college-aged young adults were repeated 30 times for three popular ICA algorithms.

Our main result is a polynomial-time algorithm for ICA using only a nearly linear number of samples. Since each column of Acan only be recovered up to a scaling of the column, we can assume w.l.o.g. that sis isotropic.

This paper relates to the separation of single channel source signals from a single mixed signal by means of independent component analysis (ICA). The proposed idea lies in a time-frequency representation of the mixed signal and the use of ICA on spectral rows corresponding to different time intervals.
