Channel estimation and training sequence design for spatially correlated fading in Multiple Input Multiple Output with Orthogonal Frequency Division Multiplexing (MIMOOFDM) systems are still open research topics of great interest. In this paper, we investigate the Linear Minimum Mean Square Error (LMMSE) channel estimation for MIMO-OFDM systems in spatially correlated fading channels. We find the lower bound of the Mean Square Error (MSE) of channel estimation. We also propose a class of training sequences which almost achieve the performance of optimal training sequences. The effectiveness of the proposed training sequences is demonstrated empirically by simulation results. © 2008 IEEE.
