| Wireless communication technology has become an important part of today's world, with the continuous development of communication technology, the future of communications (4G) of the most basic requirement is that broadband high-speed data transmission. And thus the introduction of MIMO-OFDM technology, has been widespread concern, MIMO-OFDM technology allows the wireless system during transmission with high reliability and validity of its high-speed wireless transmission applications, a strong contender. MIMO-OFDM system for time and frequency offset is extremely sensitive, so synchronization for MIMO-OFDM system is critical and is an important part of communication systems.In this paper, for MIMO-OFDM system, focus synchronization technology. First the basic principles of MIMO-OFDM system is introduced. And some key technologies of the system so described. Analysis of synchronization error on the system affected, and further reflects the importance of synchronization. Algorithm for OFDM system summary, in this based on the multi-antenna system synchronization algorithm research and analysis. The same time, this paper, a burst communication system in the next synchronization algorithm has a better performance, mainly based on two identical training component and the back flip suffix calculated as the cyclic prefix,Through the simulation results validate the synchronization method has good performance. |
