摘要
介绍了一种新型的短波高速跳频通信系统──ＣＨＥＳＳ系统，描述了ＣＨＥＳＳ系统的结构并对其性能进行了分析。重点讨论了ＣＨＥＳＳ系统的核心技术—差分跳频技术（ＤＦＨ），提出了一种相关跳频编码方案。用计算机模拟实现了ＣＨＥＳＳ系统的调制解调、编码解码过程，由此验证了ＣＨＥＳＳ系统的可行性。
This paper presents a new high speed HF Radio called CHESS. The composition of CHESS is dicussed and the performance of CHESS is analyzed. The key technology which is called DFH(Differential Frequency Hopping) is discussed. A coding project of Correlated FH are presented. The modulation and demodulation. code and decode of CHESS are simulated with the computer. After the simulation, the feasibility of the CHESS is verified.
