“…HF communication plays an important role in the field of modern remote communication. With the advantages of anti-multipath time-delay broadening of HF channel effectively and equalizing simply, the technology of HF OFDM modulation-demodulation has gradually been the research hotspot of modern HF communication [1,2,3]. Due to the effect of multipath fading and Doppler frequency shift, HF channel is the frequency and time selective fading channel.…”

In the field of the application of modern HF communication, much more attention is paid to the technology of HF OFDM modulation-demodulation. HF channel is the frequency and time selective fading channel. To reliably receive information, HF receiver must estimate real-time channel parameters to equalize. A performance comparing with the channel parameters estimate methods based on the first-order linear interpolation, Gaussian interpolation, Cubic interpolation and DFT interpolation is analyzed. Simulation results show that a better performance will gain when using DFT interpolation channel estimate method in HF OFDM system.
