无线信道中存储转发模式的丢包率估计

PLR Estimation of SAF In Wireless Communication Channel

文中通过理想化无线信道,并提出相对应的合理假设,建立了一种简化的无线信道模型。利用随机过程理论中的马尔可夫链分析方法,对存储转发系统在该信道模型中的工作情况做了分析,估计了该系统的丢包率,并得到相应的结论。

This article describes a simplified wireless channel model, which is based on idealization of the wireless channel in reality and some rational corresponding assumptions. By utilizing Markov Chain in stochastic process theory, the working condition of SAF（Store and Forward） mecanism in the above channel model is analyzed. Then the PLR （Packet Loss Rate） in the wireless system is evaluated. And the corresponding conclussion is finally drawn.
