摘要
本文提出了一种用于卫星广播信道的选择重发型一点对多点数据通信协议,并进行了理论分析和计算机模拟.结果表明,选择重发型 PMP 协议的性能优于集中反馈选择重发型 PMP 协议.在信道速率越高时,这种优势越明显.
In this paper,a selective-repeat ARQ point to multipoint data commu- nication protocol used in the satellite broadcast links is presented.Theoretical analysis and computer simulation is carried out,which shows that this method is better than send-and-wait ARQ protocol.The higher the channel rate,the more advan- tages the protocol reveals.
