| 摘 要： | MIMO-OFDM技术是未来无线通信系统研究热点，而信道估计是实现MIMO-OFDM系统优良的传输性能的重要环节．笔者在对国内外现有MIMO-OFDM系统的信道估计方法综述的基础上，分析和比较基于导频符号的非盲信道估计方法、盲信道估计方法和半盲信道估计方法的优缺点，并解决算法的复杂度和应用性的矛盾问题，因此认为，半盲信道估计方法将成为未来信道估计研究的重点．

| Abstract: | The research on MIMO-OFDM has received much attention in wireless communication system in the future, while the channel estimation is an important aspect to achieve high transmission performance for MIMO- OFDM systems. On the basis of the reviewing on the available channel estimation methods for MIMO-OFDM, analysis and comparison with the advantages and disadvantages of pilot symbols aided on no blind channel estimation method, blind channel estimation method and semi blind channel estimation method are discussed. Finally, it can be concluded that semi blind channel estimation will be the research focus of channel estimation for compromise between complexity and application of the channel estimation algorithms. |
