摘　　要：针对短波数据通信的特点,提出了一种可靠多播中反馈信息的信道争用方式,使第二代短波通信实现可靠多播传输。同时将改进的可靠多播协议RMTP应用到短波可靠多播传输中,首次提出"一层发送,逐层补充,分层分步反馈"的思想。通过仿真表明,改进后的RMTP协议满足可靠多播传输要求,与未使用该协议的可靠多播传输相比多播传输延时明显缩短。With the characters of HF data communication,in order to make reliable multicast protocol be used in the 2nd generation HF condition this paper raises a new channel contention method for the feedback message.Then it uses a modified RMTP（Reliable Multicast Transport Protocol） for HF reliable multicast transportation.First it uses a way of＂transport in one layer,more layers repair,and feedback in different layers on different time＂.After the simulation,the results show that this kind of RMTP which has been developed can meet with the demand,and reduce the time for reliable multicast compared with that not using this improved protocol.
