Abstract :
The EM iterative algorithm is commonly used in recent years for missing data, which has the character of easy and popular applicability. But the EM algorithm has a fatal weakness that is slow convergence speed; base on that EM acceleration algorithm is proposed in order to solve the problem. In non-Gaussian noise simulation numerical is carried out, the results show that the proposed algorithm has a good performance, and compare with EM algorithm, the convergence speed is better than standard EM algorithm.
