摘要
文章提出了一种将差分跳频技术应用于短波窄带猝发通信的思想。分析了窄带情况下差分跳频的跳速与最小频率间隔、跳频频率集点数、最小自由距之间的关系以及短波窄带差分跳频猝发通信的数传速率。从理论上证明了在最小自由距和数传速率方面窄带差分跳频能满足猝发通信的要求。最后进一步举例分析了数传速率的冗余与编码效率之间的关系。
In this paper, an idea about applying Differential frequency hopping（DFH） in High Frequency（HF） Narrowband burst-communication is proposed. This paper describes the relationship of frequency hopping speed in narrowband HF DPH with the minimum frequency interval, frequency sets＇ hopping number and the minimum free analyzes the data transmission rate of HF Narrowband DFH Burst Communication. It proves theoretically narrowband DFH can meet the requirements of Burst Communication on the minimum free distance and transmission rate. Finally, this paper calculates the coding efficiency when the data transmission distance that the the data rate is redundant.
