摘要
介绍了MIMO-OFDM系统基本模型,并论述了MIMO-OFDM关键技术。MIMO-OFDM技术是分别吸收MIMO技术和OFDM技术的优点发展而来的通信新技术,在MIMO系统中,天线阵列采用线性天线阵列,并沿着水平线分布,从而实现了信号的空间分集。MIMO-OFDM系统在通信的发展过程中,起到了至关重要的作用。
This paper introduces the basic model of MIMO-OFDM system,and discusses the key technology.MIMO-OFDM MIMO-OFDM is the development advantages of absorption of MIMO and OFDM technology and new communication technology,in the MIMO system,using a linear antenna array antenna array,and distributed along the horizontal line,so as to realize the signal space diversity.MIMO-OFDM system in the development process of communication in the play a crucial role.
