MIMO-OFDM is one of the promising schemes for achieving high data rate and large system capacity over wireless communication system. In this paper, combining MMSE with FRLS algorithms, we propose a joint channel estimation scheme for wireless environments in MIMO-OFDM systems. Compared with traditional MMSE channel estimator, the new method is more accurate and efficient proved by simulation.
