为了研究多输入多输出（MIMO）技术在HF波段内通信的潜在适用性，在英国达勒姆和莱斯特之间的255 km无线电路径上进行了测量。本文介绍了紧凑的异质天线阵列的实验结果。这些实验的结果表明，传统的间隔HF天线阵列可以被替换为紧凑的，有源的，异构的阵列，以实现所需的各种天线元件之间的去相关的水平。还提出了一个案例研究的例子，突出了电离层的可变性质的HF-MIMO无线电链路的背景下的重要性。
Measurements have been made over a 255 km radio path between Durham and Leicester in the UK in order to investigate the potential applicability of multiple input multiple output (MIMO) techniques to communications within the HF band. This paper describes the results from experiments in which compact heterogeneous antenna arrays have been employed. The results of these experiments indicate that traditional spaced HF antenna arrays can be replaced by compact, active, heterogeneous arrays in order to achieve the required levels of decorrelation between the various antenna elements. An example case study is also presented which highlights the importance of the variable nature of the ionosphere in the context of HF‐MIMO radio links.
