一种短波MIMO系统模型及适用性分析

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。

HF MIMO system modeling and its applicability analysis

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 MIMO system.
