摘要
在多入多出(MIMO)系统原理和模型的基础上,分析了基于单入单出(SISO)、单入多出(SIMO)、多入单出(MISO)以及MIMO系统的信道容量.利用MATLAB语言,基于瑞利衰落信道,分别仿真了以上四系统的信道容量,并比较了不同天线数目的MIMO系统的信道容量.通过搭建MATLAB仿真平台,说明了MIMO系统可以大幅增加信道容量.MIMO通信系统能满足无线通信系统高质量、高速率要求.
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.
