This paper relates to the separation of single channel source signals from a single mixed\nsignal by means of independent component analysis (ICA). The proposed idea lies in a\ntime-frequency representation of the mixed signal and the use of ICA on spectral rows\ncorresponding to different time intervals. In our approach, in order to reconstruct true sources, we\nproposed a novelty idea of grouping statistically independent time-frequency domain (TFD)\ncomponents of the mixed signal obtained by ICA...............................
