Multi-element antenna arrays have long been employed at receiver sites to obtain spatially separated samples of the incoming wavefield at a receiver which are then combined by a variety of techniques ranging from the simple to the complex to reduce the deleterious effects of multi-path fading. In recent years, the mobile radio community has been investigating techniques in which arrays of antennas are employed at both the transmitter and receiver (rather than just at the receiver as previously) with the aim of significantly increasing the data throughput capacity within a fixed bandwidth by exploiting the presence of multipath propagation. These are known as MIMO (multiple input / multiple output) systems. The aim of this proposed project is to undertake an experimentally based investigation on the potential applicability of MIMO techniques to communications within the HF band.

长期以来，多单元天线阵列一直被用于接收端，以获取接收端入射波场的空间分离样本，然后通过从简单到复杂的各种技术将这些样本组合起来，以减少多径衰落的有害影响。近年来，移动无线电界一直在研究在发射机和接收机（而不是像以前那样只在接收机）同时使用天线阵列的技术，目的是通过利用多径传播的存在来显著提高固定带宽内的数据吞吐量。这些被称为MIMO（多输入/多输出）系统。这个提议的项目的目的是进行一个基于实验的研究，研究MIMO技术在高频频段内通信的潜在适用性。
