  • In this paper, allied strategy is introduced into PSO and a parallel and two-stage blind signal separation based on particle swarm optimization (parallel particle swarm optimizationgradient algorithm) is proposed. This algorithm is characteristic of rapid convergent speed and high separation precision. The simulation results show that this algorithm proposed is superior to particle swarm optimization in which allied strategy is not applied, and this algorithm is superior to traditional gradient algorithm and genetic algorithm in convergent speed and separation effect.
