Abstract

Contraposing the diffuse characteristic of HF channel and low data rate in HF communication systems, the technology which combines AMC and OFDM was presented. The models of transmitter and receiver were also put forward. The key technologies such as time synchronization, carrier frequency offset estimation, channel estimation and PAPR reduction were analyzed and corresponding resolutions were given in this paper. The technology can improve the data rate of HF communication remarkably and has wide application prospects.
