摘要
对星间链路信道统计模型进行了理论分析,在MATLAB/Simulink平台上,设计并实现了一种星间链路仿真模型。该模型充分考虑了星间链路信道中的多普勒频移、卫星星座的周期性引起的自由空间传播衰减,以及链路中存在的干扰、噪声、时延等对卫星通信信号的影响。仿真结果证明了该模型的正确性。
In this paper, the statistical model of inter-satellite link is analyzed. A MATLAB/Simulink based inter-satellite link communication simulation is designed and implemented. The loss of transmitting caused by Doppler frequency shift and the period of satellite constellation, inevitable interferences, noise and delay are considered in this model. The simulation result shows that the model is correct.
