Abstract

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.
