We investigate a channel estimation technique based on a comb-type pilot arrangement for a MIMO OFDM system. Especially, when the channel varies with time, an efficient channel estimation technique with channel correlation is proposed for accurate estimation. Simulation results show that the proposed channel estimator is accurate and effective for tracking variations of channels between multiple transmit antennas and receive antennas in time-varying radio channels.
