| Abstract: | This paper describes a 4800bps single tone HF MODEM, and focus on the adaptive equalization and error control coding required by high speed data transmission. Computer simulation results are given. Compared with MIL - STD - 188 - 110A, the performance of the HF MODEM in the white noise channel is improved 4dB, the one in the multipath fading channel is also improved greatly. |
