摘　　要：本文讨论了在多输入多输出( Multiple- Input Multiple- Output,MIMO)信道上传输的基本容量极限。首先假设信道矩阵是独立的复高斯变量,按照这种理想环境推导出MIMO信道容量;This paper discussed the basic capacity limit of transmission on the multi-input multi-output channels. Firstly, the capacity of MIMO channel was calculated under ideal condition, which the channel matrix is independent, complex Gaussian variables; Finally, it is educed that MIMO system can improve the channel capacity greatly by the analysis for a few capacity of fixing coefficient channels.
