| Abstract: | The paper discusses the system principle and main algorithms, including MODEM/DFE design, adaptive equalization algorithm, carrier frequency recovery algorithm, timing synchronization algorithm, error controlling principle, principle of transmission rate alteration of information,and system joint adjusting principle, for a Single-Tone Serial HF MODEM which is implemented based on a DSP platform. The results of a real time data transmission experiment over telephonelink and radio links are also given in this paper. |
