在现有Gesbert多输入多输出（MIMO）系统模型的基础上，结合短波天波信道的传播特点，建立了一种短波MIMO系统模型。所建立的模型是一种解析模型，可由接收天线相关矩阵、发射天线相关矩阵以及传播模式相关矩阵产生。通过对该模型进行适用性分析发现，其与实际HF MIMO系统的信道矩阵具有相同的秩特性。该模型避免了直接测量HF MIMO信道矩阵的复杂性和局限性，可以用于进行HF MIMO系统容量计算。

A high frequency(HF)multiple input multiple output(MIMO)system model is established based on the existing Gesbert MIMO model . It adequately considers the propagation characteristic of HF communication . This HF MIMO model is analytical and can be decomposed into the corresponding correlation coefficients matrix of receiving antennas,transmitting antennas and propagating modes . After sufficient applicability analysis,it is found that this model shows the same rank as the actual HF MIMO system . This model avoids the complexity and shortage of directly measuring the HF MIMO channel matrix and can be used to compute the capacity of HF MI-MO system.
