摘　　要：研究了在无线MIMO(Multiple-Input Multiple-Output)系统中,天线相关时,发射端已知信道状态信息(CSI)和未知CSI两种情况对系统容量的影响。建立了天线相关MIMO系统模型,给出了相关系数并推导了相关信道容量的表达式,用Monte Carlo方法仿真了天线角度扩展为均匀分布时,信道状态信息与系统容量之间的关系。This paper studies and simulates the capacity of correlation channel in MIMO system with CSI and without CSI. First, the MIMO system model with antenna correlation is introduced, the correlation parameter is given and the expression of correlate channel capacity is deducted. Second, by using Monte Carlo method, we simulate the relationship of channel capacity and CSI in MIMO system with channel correlation, when the antenna angle extends to uniform distribution.

关 键 词：多输入多输出 信道状态信息 信道容量 信道相关性
