Abstract: Based on the comprehensive analysis of OFDM and MIMO, this paper also
discusses some aspects, which are closely related to MIMO technology. Through the
development of space resources,MIMO technology utilizes spatial multiplexing and space
-time coding to provide multiplexing gain and diversity gain for system.It can provide
maximum transmission rate. At the same time, it also improves transmission reliability.
The combination of OFDM and MIMO is the core of high-speed WLAN technology.
