摘要
多媒体业务对无线通信的带宽与品质提出了更高的要求,OFDM和MIMO由于满足了这一需求被越来越多的无线通信标准采用所为底层的调制和传输技术。频率同步问题是OFDM-MIMO物理层设计中正确解调的前提和基础,本文介绍了OFDM-MIMO的原理、特点和频率同步问题的研究现状。
Multimedia put forward higher requirements for wireless communication. Because of satisfying these requirements, OFDM and MIMO is adopted by more and more wireless communication standards in their physical layer. Frequency synchronization is an important problem in the physical layer design of OFDM-MIMO and is the basis of correctly demodulation. This paper introduces the basic principle, characters and frequency synchronization researches of OFDM-MIMO.
