摘　　要：传统的低轨卫星容量计算只采用单一的链路模型进行分析,忽视了同一地区链路可能存在不同状态的实际情况。采用二状态的马尔可夫信道链路模型,可以对农村地区的链路做出更准确的估计。考虑由于链路时延产生的功率控制误差,可使低轨卫星通信系统容量分析更贴近实际条件。Only one kind of communication link state model is considered in the traditional analysis of the capacity of LEO communication satellite system,which neglects the truth that one district may have different kinds of link states.With the use of twostate Markov link state model,we can estimate the link state of rural district more accurately.In consideration of the power control error caused by the transmission delay,the calculation of capacity in this paper is much more closer to the truth.
