多输入多输出（MIMO）的概念已经成为无线通信领域中的富有成效的研究领域，其目的在于提供增加的数据吞吐量。然而，到目前为止，MIMO研究主要集中在VHF，UHF和SHF频段内的短距离通信上，很少有研究将MIMO技术用于HF频段内的长距离通信。在2007年9月至2008年9月期间，进行了几次实验活动，以研究在HF波段内应用MIMO技术的可行性。本文介绍了从达勒姆到英国莱斯特的255公里路径上的测量结果，特别强调在发射机和接收机上使用异构天线阵列。
The concept of multiple input multiple output (MIMO) has become a productive area of research in the field of wireless communications with the aim of delivering increased data throughput. However, to date, MIMO research has focused primarily on short‐range communications within the VHF, UHF, and SHF bands, and very little research has been conducted toward exploiting MIMO techniques for long‐range communications within the HF band. Between September 2007 and September 2008, several experimental campaigns were conducted to investigate the feasibility of applying MIMO techniques within the HF band. The results of measurements over a 255 km path from Durham to Leicester within the United Kingdom are presented in this paper with particular emphasis on the use of heterogeneous antenna arrays at the transmitter and receiver.
