摘要 本文主要针对M IMO-OFDM系统中的导频信道估计技术进行了阐述,首先对我们采用的仿真系统进行了简单的描述,接着较为详细的介绍了我们采用的时频二维信道估计技术的原理,在第三部分,对采用的导频的正交性进行了分析;最后利用仿真测试的结论,验证了算法的有效性和鲁棒性。 The estimation of the channel is mainly discussed in this thesis through the pilot,firstly we describe the MIMO-OFDM systems, especially introduce the theory the estimation of the time-frequence channel in detail, secondly, the means of the orthogonality of the pilot is analysed, finally the algorithm is valid and robust in the Matlab.
