摘要：
Based on the analysis of the model of MIMO-OFDM systems, a novel scheme of pilot symbols and the maximum likelihood estimation method are proposed to estimate the MIMO-OFDM channel, and the performance of the scheme is analyzed. The result of computer simulation shows that under the conditions of having no any knowledge of the channel statistics and the SNR, the efficiency of pilot symbols is high and the performance of the proposed scheme is superior to that of other methods, such as RRE and LE.
