摘　　要：针对G-E信道,设置有限的缓存容量,根据信道状态动态调整发送端的发送状态,建立了将信道状态和缓存中等待传输分组数合并后的多状态Markov模型,给出了系统的状态转移矩阵,求得了系统各状态稳态分布和分组丢失率的解析式.Based on G-E channel and the set buffer capacity of the system,the sender adjusts the sending state according to the channel state variation.The Multi-state Markov model is generated after the channel variational state and the number of packets waiting for transmission in the buffer are united.The state transition matrix is given and the expressions of packet loss rate and the steady-state distribution of each state are obtained.

关 键 词：G-E信道 分组丢失率 MARKOV模型 稳态分布
