• Conventional methods
• Differential kurtosis
• Instantaneous mixtures
• Non-stationary sources
• Second order statistics
• Sub-Gaussians
• Super-Gaussian
• Time domain

The sources extraction from their underdetermined instantaneous mixtures via time- domain is presented in this article. Firstly, an algorithm based on differential kurtosis to separate non-stationary sources with underdetermined case one by one is introduced. Then the rest sources are recovered by using an algorithm based on second-order statistics. The simulation results show that the proposed method can separate sources of super- and sub-Gaussian distribution, and its superior performances to other conventional methods.
