Multiuser detection based on the EM iterative algorithm in non-Gaussian noise

Because of the different interference in existence, signal will be inevitably eroded while transmitting. The EM iterative algorithm is commonly used in recent years for missing data, which has the character of easy and popular applicability. So based on the EM iterative algorithm multi-user detection is proposed. In non-Gaussian noise simulation numerical is carried out, the results show that the proposed algorithm has bad performance in non-Gaussian noise, but convergence of variations less with robustness.
