On Research Advances and Development Requirements of High Frequency Communication Technologies

High frequency (HF) communication, which has the advantages of long transmission distance, quick starting, high flexibility and convenient networking, is an important means of military and emergency communications. Focusing on the basic problems of effectiveness and reliability of information transmission in time varying dispersion wireless channel, the research advances of data transmission, link establishment, anti-jamming communication and networking were first reviewed. Then, considering the development requirements of the next generation intelligent HF communication systems, some key technologies of HF ommunication were discussed, such as HF channel modeling and prediction with big data, autonomous communication under complex electromagnetic environment, active defense in the strong confrontation scenario, and multi domain integrated communication for wide area heterogeneous scenarios. It is expected that this research can promote the further development of HF communication systems.
