N2 - In this paper, we propose a new method for channel estimation based on a combination of pilots and pseudopilots in OFDM systems. In the proposed method, we use just only from half of number of minimum necessary pilots that is required  to obtain  the minimum MSE of LS channel estimation with the same preceded efficiency. Also, our simulation results show that using the same number of used pilots in conventional method for channel estimation, we obtain better efficiency using proposed method in a MIMO-OFDM system.
