摘要
针对Ka频段卫星通信信道中电波传播特性的研究,通过引入SAM模型和新的影响因子,包括雨滴大小、云雾及大气吸收等,分析了降雨及多因子对信道的影响,建立了Ka频段卫星通信信道仿真模型,并基于OPNET平台进行仿真。此模型能够更好地提供清晰的数学表达式,对卫星信道的研究提供了可靠数据。
Due to radio wave propagation characteristics of Ks-band satellite channel, joining with SAM model and some new factors which include the raindrop size, clouds and atmospheric absorption, the effect scales of these factors were analyzed and researched either in this paper The channel simulation model of Kaband satellite communication based on OPNET platform was built. The results showed that high precision and validity of new model were significantly improved, through the simulation experiments.
