Aiming at these problems, an expectation maximum based MAP algorithm is proposed and the performance is analyzed. The proposed algorithm avoids large matrix operations by using the EM algorithm to decompose the MIMO channel estimation problem into a series of single input single output problems. Besides, a joint estimation is carried out over multiple OFDM symbols in order to enhance the data transmission efficiency and the estimative performance of the proposed algorithm.

该算法利用EM算法把多输入输出信道估计问题化简为一系列独立的单输入输出问题，避免了大规模矩阵运算，降低了MAP算法的计算复杂度；为进一步改善MAP算法的数据传输效率及其估计性能，可通过对多个连续的OFDM符号进行联合信道估计。
