摘要
描述了一种４８００ｂｐｓ串行ＨＦ ＭＯＤＥＭ，重点讨论了实现高速数据传输的自适应均衡和纠错编码技术，给出了计算机模拟结果。与ＭＩＬ－ＳＴＤ－１８８－１１０Ａ相比，这里给出的方案在白噪声信道下改善了 ４ｄＢ，在多径衰落信道下改善更明显。
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.
