DSP implementation of real-time blind signal separation using simultaneous perturbation method

Blind signal separation is a technique to extract original signals by using plural observed signals that are mixtures of original signals. In this paper, realization of the real-time blind signal separation using the simultaneous perturbation method is described. We use the simultaneous perturbation method to update separation matrix. Then the simultaneous perturbation method does not use probability densities of the original signals. The system is implemented on digital signal processor. Details of the implementation are described. A result is shown.
