【摘要】 提出了短波自适应抗多径调制解调方案，给出了该调制方案中的四进制调频（４ＦＳＫ）加跳频和时频调制（１６ＴＦＳＫ）加跳频的实现框图及自适应变速方法，并给出了该调制解调方案的实测性能．最后简单介绍了应用该调制解调技术的短波自适应自组织实验系统．更多还原

【Abstract】 A new modem technique for the HF communication network with dynamic data rates is proposed.The implemented blook diagrams of 16TFSK and 4FSK plus ftequency hopping anddynamic data rate changing for the modem and experimental results are given.Finally,the adaptive self-organized HF Network using the modem is described.更多还原
