摘要:短波通信受到时变电离层的影响,通信传输质量和速率受到极大限制。为了提高短波通信的可靠性,尤其是远距离短波通信的可靠性,本文提出一种基于喷泉编码技术的分布式短波通信系统,通过利用应用层的喷泉编码插件,和分布式的多部短波电台接收和译码处理,可以实现远程高可靠的通信,并且对现有的硬件设备改动极小。

Abstract:High Frequency(HF)communication channel suffers unstable ionoshpere conditions. A fountain code based HF radio system is presented to enhance the reliability of ultra-range HF radio system. Instead of upgrading hardware—employment of multi-antenna for example, the system achieves reception diversity by fountain code software. Therefore it could provide a practical solution for reliable ultra-range transmission. The simulations and optimizations verified that with a small number of radio stations’ joint effort, the brand new system guaranteed successful HF communications.
Key words:HF Radio; fountain codes; distributed network agency
