This paper researches the decision-directed channel estimation for MIMO-OFDM systems based on training sequences. For the computational complexity of conventional channel estimation algorithm is too high, we apply the simplified channel estimation algorithm in paper to the MIMO-OFDM systems, which reduces the complexity of the channel estimation. Then an improved simplified channel estimation algorithm is proposed, which further improves the channel estimation performance and no more complexity is increased.
