摘要 MIMO-OFDM技术是未来无线通信系统的研究热点。信道估计是估计出信道的时域或频域响应,对接收到的数据进行校正与恢复,是实现MIMO-OFDM系统优良传输性能的重要环节。文章对MIMO-OFDM系统的多种信道估计方法进行了探讨,分析和比较了非盲信道估计、盲信道估计和半盲信道估计方法,并提出了未来信道估计算法的研究方向。 The research of MIMO-OFDM has received much attention in the wireless communication system in the future. The channel estimation which estimates the channel response of time or frequency field, revises and recovers the data received is an important aspect to achieve the high transmission performance for MIMO-OFDM systems. A lot of the channel estimation techniques are discussed on MIMO-OFDM Systems, analysis and compare on no-blind channel estimation techniques, blind channel estimation techniques and semi-blind channel estimation techniques are emphasized. Finally, the trend of research of channel estimation in the future is proposed.
