HF wideband communication is the development direction of HF communication

the existing HF frequency management system using fixed frequency allocation approach to assign frequencies to users

which leads to poor HF spectrum utilization

which cannot meet the needs of HF wideband communications on spectrum resources.The existing ways of the HF frequency selection and its key technologies are analyzed.Current status of frequency management of HF wideband communication is summarized.Dynamic spectrum access algorithms of HF wideband communication are studied and its advantages and disadvantages are pointed out.Finally

management techniques of dynamic spectrum which is suitable for HF wideband communication are prospected.
