| Abstract: | Abstract： MIMO multi- antenna technology can greatly increase wireless communication rate and spectrum efficiency without increasing the bandwidth and power, it is one of the hot technologies. This paper firstly analyzes the channel capacity of single user and multiple users MIMO system, the performance gain system using multi antenna technology tion and the effect of MIMO system in WLAN at the end of the brings. It explains the applicapaper, By comparing with the throughput of MIMO technology in non - standard bandwith and giving an application in the dual frequency wireless ad hoc network, points out that MIMO is an effective means to improve the spectrum utilization. |
