| 摘 要： | 针对Ka频段卫星信道中降雨衰耗的统计分布特点,建立了基于离散降雨衰耗状态的卫星信道模型,模型中各状态组成离散的Markov链并由其转移概率矩阵来表示,分析此模型下的信道误比特性能和数据包丢失性能。此模型能够适用于链路层以及高层通信协议。

| Abstract: | With the consideration of the statistic distribution characters of the rain attenuation in Ka-band satellite channel, a channel model was established based on discrete rain attenuation states, in which the rain attenuation states formed a discrete Markov link denoted by the transition probability. Through the analysis of the bits error and packets loss performance, the channel model is applicable in the analysis of link layer and higher layer communication protocols. |
