It is an important breakthrough in the area of munication. The system capacity and frequency spectrum efficiency munication systems can be improved by this technology without extra frequency bandwidth and with no additional power expenditure. MIMO is ing a key technology of the new generation high data rate wireless munication system. As well known , the channel capacity munications system is the limit of the transmission rate. The analysis results of capacity can provide the theoretical basis and guidance to the actual munications system designed. T herefore, the MIMO system channel capacity analysis is an important and basic research topics. T his paper investigates the MIMO system, mainly concentrated in the capacity of the MIMO system. First of all, from the perspective of the concept of MIMO, this paper introduces the current munication technologies . Then revolves around MIMO munication system, introduces the basic principle of MIMO technology space-time coding technique and model and the capacity of MIMO system .A fter this, the paper makes a simple introduction about the simulation software MATLAB.
