英文摘要：

Application and feature of various single channel ICA algorithms （DE-ICA, WT-ICA, EMD-ICA and EEMD-ICA） are compared and analized. Results of the simulation experiments with them show practicality of the al-gorithms in the single channel signal separation, and feasibility in deformation analysis.
