摘要：短波通信受到時變電離層的影響，通信傳輸質量和速率受到極大限制。為了提高短波通信的可靠性，尤其是遠距離短波通信的可靠性，本文提出一種基于噴泉編碼技術的分布式短波通信系統，通過利用應用層的噴泉編碼插件，和分布式的多部短波電臺接收和譯碼處理，可以實現遠程高可靠的通信，并且對現有的硬件設備改動極小。

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
