For problems of Instantaneous mixed blind signal separation, a new blind source separation algorithm based on fourth-order cumulant and simple particle swarm optimization was proposed. Fourth-order cumulant was used as objective function, then the simple particle swarm optimization was uesd to optimize it. Simulation results show that the algorithm can achieve the efficient blind source separation separation for conference speech blind signal separation. Compared with other algorithms, the proposed algorithm has faster convergence speed and higher separation accuracy.
