With the large-scale construction of high-speed railway, the impact of its high speed on Orthogonal Frequency Division Multiplexing (OFDM) channel estimation has caused a wide range of concern. This paper studies the OFDM systems in high-speed railway environment and its channel estimation using least square (LS) method. In the simulations, we take into account Doppler frequency shift, antenna configuration, correlated scattering and modulation type and analyze their impacts on channel estimation. The simulation results show that the bit error rate (BER) performance is increased by 2~5dB when the number of transmit antennas is doubled and SNR is greater than 10dB. The BER performance of correlated scattering is between those of completely independent and fully correlated.
