Abstract
In this paper, we do research about Expectation Maximization (EM) Algorithm for MIMO-OFDM systems (Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing). The EM algorithm is analyzed and used to channel estimating and channel tracking. It is shown that EM is an efficient iterative algorithm which can adapt to the fading channel for MIMO-OFDM system.
