Abstract

The HF band, located in between 3 – 30 MHz, can offer single hop communication channels over a very long distances – even up to around the world. Presumably, this advantage takes its toll which shows as a quite bad behaving communication channel. Traditionally the HF is seen primarily as a solution for long communication ranges although it may also be the perfect choice for much shorter communication ranges when a high data rate is not a primary target. By choosing the used HF channels wisely, i.e., cognitively, the channel behavior considerably improves. In this paper is discussed about a change of paradigm in HF communication that will take place after applying cognitive principles on the HF system. The foundation for this in the form of much higher data rates is in the improvements on HF physical layer that for example DRM (Digital Radio Mondiale) and MIL-STD-188-110C has introduced.
