摘　　要：本文探讨了在卫星信道上,以分组(Packet)形式按HDLC规约传输数据时,传输参数分组长度和滑动窗尺寸同时优化以提高信道利用率的问题。文中提出了数学模型,导出了具有一般意义的结论;报告了笔者所研制的“卫星分组通信处理器”及在卫星SCPC话音通道进行分组数据传输的试验结果。Optimizing the transmission parameters-packet length and sliding window simultaneously to maximize the transmission efficiency of satellite link, when data transfer via satellite link by packet form basing on HDLC protocol, is discussed in this paper.A mathematical model is suggested and the general conclusions are derived. Finally, the Packet Satellite Communication Processor and the experimental results are reported.
