| Abstract: | In this paper, based on the analysis of the HF communication channel, a small type data terminal used in HF communication is presented. The key technipues used in the system are: Combined Frequency and Time-Shift keyed Transmission System, Reed-Solomon error-correction Code, Interleave-Deinterleave technique and correlated preamble detection. The analytical and experimental results have shown that this terminal in satisfactory. |
