摘要
在卫星与地面终端之间的星地链路中,存在复杂多变的信道环境,这些因素对系统的切换性能有着重要影响。文章首先建立星地信道模型,并将此模型应用于切换过程,通过仿真得到信道特性对于切换性能的具体影响。
There are complex and time-varying channel conditions between LEO satellite and terrestrial users, these factors would have important impact on handover performance. This paper constructs channel model first and applys the model in the process of handoff. At last,the influence of channel model on handoff performance is got by simulation.
