| Abstract: | This article analyzes the channel capacity of Single Input Single Output （SISO）, Single Input Multiple Output （SIMO）, Multi Input Single Output （MISO） and Multi Input Multi Output （MIMO） based on the basic theory and model of MIMO. Based on Rayleigh Fading Channel, the channel capacity of the four systems are simulated respectively using MATLAB language. And Channel capacities of MIMO system simulates with different numbers of antennas is also compared. It is proved that MIMO system can improve the channel capacity greatly by building MATLAB simulation platform. MIMO system can meet the needs of high quality and high speed of wireless communication system. |
