基于时延约束的半双工短波数据通信ARQ技术

ARQ protocol based on time delay in half-duplex HF data communication

在对短波信道特性分析的基础上,提出一种基于时延约束的改进型自动请求重传(ARQ)协议机制,降低了数据传输的时延,提高了通信效率,满足了半双工模式下短波数据传输的时效性要求。最后给出了仿真结果以及具体实现方法。

After having analyzed the channel character of high frequency communication, an advanced ARQ protocol based on time delay was proposed. It reduced the time required for transmission, and improved the communication efficiency, therefore, achieved the time limitation of data communication in half-duplex mode. Finally, the emulation and the concrete method were presented.
