Abstract

For the intelligent algorithm, it is easy to fall into local optimum when implementing blind source separation, and the convergence speed is slow, this paper proposed a blind source separation algorithm based on Givens transform and second-order oscillator particle swarm optimization. This algorithm constructed the functional relationship between the inertia weight and the learning factor, and adjusted the algorithm together to improve the algorithm's overall and global search ability. The second-order oscillation increased the diversity of the population, so the algorithm was not easy to fall into the local optimum. In addition, the algorithm used Givens transformation to convert the separation matrix into a rotation angle representation to reduce the complexity and accelerated the convergence speed. Simulation results show that the algorithm can effectively achieve the blind separation of mechanical vibration signals and speech signals, and has faster convergence speed and better separation performance than other algorithms.
