短波信道数据传输纠错方式的研究

Study of the Error Control Method of Data Transmission on Short-wave Channels

针对短波信道的特点，对短波通信数据组网进行了探讨，分析研究了SW-ARQ和SRP-ARQ 2种差错控制方式，并在不同信道误码率下对2种纠错方式的链路利用率进行了比较。根据理论研究和实际测试结果采用选择重发连续SRP-ARQ作为文件传输的纠错方式，使系统具有更好的链路利用率。

This paper discusses the short-wave telecommunication network based on the characteristics of short-wave channel. It analyzes two methods of error correction:SW-ARQ and SRP-ARQ ,and compares the link efficiency of two methods at different bit error rate. According to the research and testing,the SRP-ARQ is chosen as the error correction method for file transmission to achieve a higher link efficiency.
